The ratio between the length and the breadth of a rectangular park is 5 : 3. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 min, then thearea of the park (in sq. m) is?	Choose the correct choice from the following answers:
A) 124545 m B) 134561 m C) 156787 m D) 15450 m E) 150000 m
Perimeter = Distance covered in 8 min. = 12000 x 8 m = 1600 m.   60   Let length = 5x metres and breadth = 3x metres.   Then, 2(5x + 3x) = 1600 or x = 100.   Length = 500 m and Breadth = 300 m.   Area = (500 x 300) m2 = 150000 m   150000 m
