176 Square Yards :)

Have a nice DAY

The area of cement needed is 176 yd².

What is area?

The area is the region bounded by the shape of an object.

First,

Area of two trapezoids

=1/2* 2 (12+ 20)*4

=128 yd²

Area of two smaller rectangles

=2 (l * b)

=2 *4 *6

=48 yd²

Thus, the area of cement needed is = 128 + 48 = 176 yd²
