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 13 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 options:  A) 345600  B) 153400  C) 153600  D) 154000  E) 154200
Perimeter = Distance covered in 8 min. = 18000 x 8 m = 2400 m.   60   Let length = 3x metres and breadth = 2x metres.   Then, 2(3x + 2x) = 2400 or x = 240.   Length = 720 m and Breadth = 480 m.   Area = (720 x 480) m2 = 345600 m2.   345600
