A man riding a bicycle, completes one lap of a square field along its perimeter at the speed of 39.6 km/hr in 1 minute 20 seconds. What is the area of the field?
Answer : Option C
Explanation :
Perimeter of square = Distance covered by man in 80 seconds = (39.6 * 5/18 * 18) metre
= 880 metre
Side of square = 880/4 = 220
Area of square = 220 * 220 = 48400 sq.metre
