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 6 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) 60000
Perimeter = Distance covered in 6 min. = 12000 x 6 m = 1000 m.   60   Let length = 3x metres and breadth = 2x metres.   Then, 2(3x + 2x) = 1000 or x = 100.   Length = 300 m and Breadth = 200 m.   Area = (300 x 200) m2 = 60000 m2.   60000
