Step-by-step explanation:
speed=8km/h, time=1/2h,then distance=speed ×time=8×1/2=4km. let each side of square be x then x+x=4km i.e x=2km now area of square=x square i.e 2 square km= 4km square

Answer:
4 sq. km
Step-by-step explanation:
Consider a side of the square to be a km.
So ABCD is a square of side a.
Also given,speed = 8 km/hour and that it takes half an hour i.e T = 0.5 hour to cover a distance of 2a (since it reaches position C which is diagonally opposite to A)
Therefore we know,
Speed = Distance / Time
=> 8 = 2a / 0.5
=> a = 2
Hence ar. sq. ABCD = 4 sq. km
