Correct answer: The area of any quadrilateral can be determined by multiplying the length of its base by its height. Since we know the shape here is square, we know that all sides are of equal length. From this we can work backwards by taking the square root of the area to find the length of one side.

For example, if a rectangle has an area of 20 square feet and a length of 10 feet, divide 20 by 10 to get a width of 2 feet. Multiply the length times 2 and subtract this figure from the perimeter, if you're given these values. Then divide by 2 to find the width.

The area of a rectangle is equal to its length multiplied by its width. This equation is represented by A=L*W. If you have only the area and width, you can use the same equation to solve for the area. For example, if the area is 60 and the width is 5, your equation will look like this: 60 = x*5.

Correct answer: 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.

Because both the length and width of a square are equal, the area of a square is a2, where a is the length of a side. Since there are 6 identical sides of a cube, to find the surface area, simply multiply the area of one side times 6.

Area is 2-dimensional: it has a length and a width. Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. ... A = L * W where A is the area, L is the length, W is the width, and * means multiply.

In other words, the area of a rectangle is the product of its length and width. That is, A = l x w where l is the length and w is the width of the rectangle. For example, the area of a rectangle of length 35 m and width 25 m is 35 times 25 or 875 square meters.

Since a square has sides that are all the same length, the formula just requires us to square the length of one side, which is the same as multiplying the width and the height. Area = length of one side = 6 cm = (6 cm)2 = 6 cm x 6 cm = 36 cm2.

The area of a rectangle (A) is related to the length (L) and width (W) of its sides by the following relationship: A = L ⋅ W. If you know the width, it's easy to find the length by rearranging this equation to get L = A ÷ W.

The area of a rectangle (A) is related to the length (L) and width (W) of its sides by the following relationship: A = L ⋅ W. 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.

Area is measured in square units. The area of the rectangle can be calculated using the following formula: A = l   w, where l represents the length and w represents the width. Perimeter is the length of the boundary of the shape. It can be calculated adding the measurements of each side.
