Question

area of a square field is 15625 m square A man cycles along the its boundary at 25 m per second in how much time you will be returned to the starting point

Answer 1

Area of square field = 15625 m²

Length of 1 side = √15625 m² = 125 m

Perimeter of square field = 4 × side = 4 × 125 m = 500 m

Let the time taken to return to starting point be x

To return to starting point, the man would have to cover the whole boundary

Speed × Distance = Time

Thus,

25 m/s x = 500 m

x = 500 m ÷ 25 m/s

x = 20 seconds
