what is the length of a rectangle with width 20 in. and area 156 in.^2

1 answer

To find the length of a rectangle, you need to know its width and area.

The formula for the area of a rectangle is:
Area = Length x Width

Given that the width is 20 inches and the area is 156 square inches, we can plug these values into the formula:

156 = Length x 20

To solve for Length, divide both sides of the equation by 20:

Length = 156 ÷ 20

Length = 7.8 inches

Therefore, the length of the rectangle is 7.8 inches.
