Answer 1

Problem hassan built a fence around a square yard. It took 500 feet^2of lumber to build the fence. The fence is 5 feet tall.

Let say square yard = x * x feet²

Perimeter of Square yard = 4x  feet

Height of fence = 5 feet

Area of fence = 4x * 5 = 20 x feet²

20x = 500

=> x = 25

Area of square yard = 25 * 25 = 625 feet²

625 feet² is the area of the yard inside the fence
