Finding Length and Width When You Know Area and Perimeter If you happen to know the distance around the rectangle, which is its perimeter, you can solve a pair of equations for L and W. The first equation is that for area, A = L ⋅ W, and the second is that for perimeter, P = 2L + 2W.

Multiply the length and width together. Once both measurements are converted into meters, multiply them together to get the measurement of the area in square meters. Use a calculator if necessary.

The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width. You will often encounter word problems where two of the values in one of these formulas are given, and you are required to find the third. Example 1: The perimeter of a rectangular pool is 56 meters.

['Remember the formula for perimeter and area of a rectangle. The area of a rectangle is a = length * width, while the perimeter is p = (2 * length) + (2 * width)', 'Substitute the known values into the area formula. 36 = 4 * w. ... ', 'Substitute values for length and width into the perimeter formula.']

To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.

Assuming the room is square or rectangular, you would measure the length and width. Multiply the length by the width to get the area, and add twice the length to twice the width to get the perimeter.

Area of a rectangle formula To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

A rectangle will have the maximum possible area for a given perimeter when all the sides are the same length. Since every rectangle has four sides, if you know the perimeter, divide it by four to find the length of each side. Then find the area by multiplying the length times the width.

Set it up! Find the perimeter of the following rectangle by using the formula P=2L+2W, where L represents the legth and W represents the width of the rectangle. To find the perimeter, let L=2x+3 (the legth) and W=x+1 (the width) and plug these values into the formula P=2L+2W.

Determining Length or Width When You Know the Other If you know the width, it's easy to find the length by rearranging this equation to get L = A ÷ W. If you know the length and want the width, rearrange to get W = A ÷ L. Example: The area of a rectangle is 20 square meters, and its width is 3 meters.

Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Remember the formulas for both area and perimeter of a square. The area of a square is a = s 2, or side times side, while the perimeter is p = 4s, or 4 times s.
