Answer:
36 meters²
Step-by-step explanation:
Hassan built a fence around a square yard. It took 48 meters^2 of lumber to build the fence. The fence is 1.5 meters tall.
Let say square yard = x * x meters²
Perimeter of Square yard = 4x meters
Height of fence =1.5 meters
Area of fence = 4x * 1.5 =6x meters²
6x = 48
Divide both sides by 6
x = 8
Area of square yard = 6 × 6= 36 meters²
36 meters² is the area of the yard inside the fence
