The area of a rectangle with width x and length y, for instance, will be

A = x + x + x . . . . . y times

when the widths are added up till the end of the other side. So,

A = x \times y

. Because of this, the width and length of the rectangle's area are equal.
The rectangular fence's area is stated to be 500 square feet, and its width is stated to be 20 feet. Let L feet be the fence's length.
The rectangle's area is calculated using the formula
