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 8 minutes, then the area of the park (in sq. m) is? Choose the correct choice from the following.
A) 153600 B) 153629 C) 151299 D) 153129 E) 152109
Let length = 3x metres and breadth = 2x metres.   Then, 2(3x + 2x) = 1600 or x = 160.   Length = 480 m and Breadth = 320 m.   Area = (480 x 320) m^2 = 153600 m^2.   153600nswer: 153600
