There are numerous ways to observe a missing dimension of a rectangle, and the method yous employ will depend on what data you already have. As long as you know the area or perimeter, too as the length of one side of the rectangle (or the relationship betwixt the length and width), you can detect a missing dimension. The properties of a rectangle are such that you can use these methods for finding the width or length.

1. 1

2. ii

   Plug the values for surface area and length into the formula. Brand sure you substitute for the correct variables.

   • For instance, if you are trying to find the width of a rectangle that has an area of 24 square centimeters, and a length of 8 centimeters, your formula will look like this:
     ${\displaystyle 24=8w}$

3. 3

   Solve for $$ w {\displaystyle w} . To exercise this, you demand to separate each side of the equation by the length.

4. four

   Write your terminal reply. Don't forget to include the unit of measurement.

2. 2

   Plug the values for perimeter and length into the formula. Make sure you lot substitute for the correct variables.

3. 3

   Solve for $$ west {\displaystyle w} . To do this, y'all need to subtract the length from each side of the equation, then divide past 2.

4. four

   Write your final answer. Don't forget to include the unit of measurement of measurement.

2. two

   Plug the values for the diagonal and side length into the formula. Brand certain y'all substitute for the correct variables.

   • For case, if you are trying to find the width of a rectangle that has a diagonal length of five centimeters, and a side length of iv centimeters, your formula volition wait similar this: ${\displaystyle 5={\sqrt {w^{2}+four^{2}}}}$

3. 3

   Foursquare both sides of the formula. You demand to do this to become rid of the square root sign, which makes isolating the width variable easier.

4. 4

   Isolate the $$ due west {\displaystyle west} variable. To practise this, y'all need to subtract the squared length from each side of the equation.

5. 5

   Solve for $$ w {\displaystyle w} . To do this, yous need to notice the square root of each side of the equation.

6. 6

   Write your final answer. Don't forget to include the unit of measurement.

1. 1

   Gear up upwardly the formula for area or perimeter of a rectangle. Which formula you use will depend on which measurement you are given. If you are given the expanse, gear up up the area formula. If you are given the perimeter, set up the perimeter formula.

2. ii

   Write the expression that describes the relationship betwixt the length and the width. Write your expression in terms of what ${\displaystyle 50}$ equals.

   • The relationship might exist given by stating how many times bigger ane side is than the other, or how many units more or less it is.
   • For example, y'all might know that the length is v centimeters longer than the width. Your expression for the length is then ${\displaystyle l=w+5}$ .

3. iii

   Replace the $$ l {\displaystyle 50} variable in your area (or perimeter) formula with the expression for length. Your formula should now only comprise the variable ${\displaystyle west}$ , which means you can solve for the width.

4. 4

   Simplify the equation. Your simplified equation might have on various forms, depending on the relationship between the length and the width, and depending on whether you are working with expanse or perimeter.^[7] Think about setting up an equation that allows you to solve for ${\displaystyle west}$ in the simplest fashion.

5. 5

   Solve for $$ w {\displaystyle w} . Again, how you lot solve for ${\displaystyle w}$ will depend on your simplified equation. Utilize the basic rules of algebra and geometry to solve.

  You carve up the volume by the height and the length. You could multiply the peak and the length with each other commencement before dividing. W = V / (H*Fifty).

• Question

  The length of a rectangle field is twice its breadth. Its perimeter is 400m. How do I find the length and breadth?

  

  Let B equal the latitude. Then 2B equals the length. Write an equation in B, stating that the perimeter is equal to twice the breadth plus twice the length. Solve for B.

• Question

  How practice I find the area of a rectangle if width and perimeter are given?

  

  Double the width, and decrease that from the perimeter. Then divide that number by two, which gives you lot the length of the rectangle. Then, multiply the effect by the width to become the area.

• Question

  How do I find the dimensions of a rectangle if the perimeter is 33 and the length equals twice the width?

  

  The length (50) is twice the width (w), and then l = 2w. The perimeter, or twice the length plus twice the width, is 33, so two(2w) + 2w = 33. That means 6w = 33; w = five½, and 2w = 50 = 11.

• Question

  Area = 40" and perimeter = 28"; how do I discover side lengths of a rectangle?

  

  Let x and y be the dimensions of the rectangle. And then xy = 40, and 2x + 2y = 28. From the kickoff equation, x = 40/y. Substituting that value of 10 into the second equation, 2(twoscore/y) + 2y = (lxxx/y) + 2y = 28. Multiply both sides of this equation by y to go rid of the denominator: lxxx + 2y² = 28y. Divide by two to simplify: xl + y² = 14y. Subtract 14y from both sides to get zero on one side, and re-conform slightly: y² - 14y + 40 = 0. Factor the left side: (y - 10)(y - iv) = 0. Set each cistron equal to zero to solve for y: y = 4, 10. That means that one side of the rectangle is 4 inches in length, and the other side is 10 inches.

• Question

  The area is 77 m^2, simply all I know about the length is that information technology's 4 m longer than the width. How practise I discover the width?

  

  Set up an equation in which the width (westward) is multiplied by four-more-than-the-width (w + iv) to equal 77. Then solve for the width.

• Question

  How practise I find side lengths of a rectangle if just area and perimeter are given?

  

  Let l and west be the length and width respectively. Gear up up equations in 50 and westward for the perimeter and the surface area. Employ either equation to solve for l in terms of due west, or vice versa, and then substitute that value of l into the other equation. That will requite you the value of w. Utilise it in either equation to find the value of l.

• Question

  One side of a square chessboard is 75 cm; how would I find the area of the board?

  

  Foursquare the side.

• Question

  If merely expanse is given, how do I find length and height?

  

  Y'all cannot find length and width if all y'all're given is area.

• Question

  If I am given the area and width, how do I go the length?

  

  Dissever area by width.

Article Summary X

To discover the width of a rectangle, use the formula: expanse = length × width. Just plug the area and length of the rectangle into the formula and solve for the width. If you don't have the area, you lot can apply the rectangle's perimeter instead. In that case, you would use the formula: perimeter = 2 × length plus ii × width. Plug the perimeter and the length into the formula and solve for the width. To learn how to find the width of a rectangle using the diagonal and the length, scroll downwardly!
