A man cycles round the boundary of a rectangular park at the rate of 12 kmph and completes one full round in 8 minutes. If the ratio between the length and breadth of the park be 3:2, then its area is: Answers:
A) 1536m2
B) 15360m2
C) 153600m2
D) 163600m2
E) None of these
Perimeter= Distance covered in 8 min   = (12000/60 *8)=

1600m   Let, length= 3x meters and breadth= 2x meters   Then, 2(3x+2x)= 1600 or x= 160   Therefore, length= 480 m and breadth= 320m   Therefore, area= (480*320)m2 = 153600 m2   ANSWER:153600m2
