calculate the effect changes in dimension of a rectangle will have on its area , if length is increased by 20 % and its breadth is decreased by 5 % ?
let l and b be 100 each 100 * 100 = 10000 l increase by 20 % = 120 b decrease by 5 % = 95 120 * 95 = 11400 14 percent increase answer : a
multiply(divide(subtract(multiply(add(const_100, 20), subtract(const_100, 5)), multiply(const_100, const_100)), multiply(const_100, const_100)), const_100)
