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 9 minutes, then the area of the park (in sq. m) is	Choose the correct choice from the following options
A) 153200	B) 153400	C) 153600	D) 194400	E) 154200
Perimeter = Distance covered in 9 min. = 12000 x 9 m = 1800 m.   60   Let length = 3x metres and breadth = 2x metres.   Then, 2(3x + 2x) = 1800 or x = 180.   Length = 540 m and Breadth = 360 m.   Area = (540 x 360) m2 = 194400 m2.   194400
