The ratio between the length and the breadth of a rectangular park is 3 : 2. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 7 minutes, then the area of the park (in sq. m) is	Choose the correct choice from the following answers
A) 153200	B) 153400	C) 153600	D) 154000	E) 117600
Perimeter = Distance covered in 7 min. = 12000 x 7 m = 1400 m.   60   Let length = 3x metres and breadth = 2x metres.   Then, 2(3x + 2x) = 1400 or x = 140.   Length = 420 m and Breadth = 280 m.   Area = (420 x 280) m2 = 117600 m2.   117600
