if each side of a square is increased by 50 % , the ratio of the area of the resulting square to the area of the given square is :
let , each side = a . then , original area = a 2 . new side = 150 a / 100 = 3 a / 2 . new area = 9 a 2 / 4 . required ratio = 9 a 2 / 4 : a 2 = 9 : 4 answer : b
square_area(add(const_1, divide(50, const_100)))
