Distance covered, 2S = 8/2 => S=2. Hence, S²=4 square units

See diagram. there seems to be confusion about this. Drawing a diagram helps often in such cases.

Distance travelled along the perimeter = 2 a

Speed = 8 km /hr

Time duration = 1/2 hr

2 a = 8 * 1/2 = 4 km => a = 2 km

Area of square field = 2² = 4 km²
