A piece of land is in the shape of a rectangle. The perimeter of the rectangle is 64m

What is the area of the rectangle if its width is 12m

Let the length of the rectangle be L and the width be W.

Perimeter of a rectangle = 2(L + W)

Given, the perimeter is 64m and width is 12m.

64 = 2(L + 12)
32 = L + 12
L = 20

Now, area of a rectangle = length x width = L x W
Area = 20 x 12 = 240 square meters

Therefore, the area of the rectangle is 240 square meters.
