calculate the effect changes in dimension of a rectangle will have on its area , if length is increased by 18 % and its breadth is decreased by 16 % ?
"let l and b be 100 each 100 * 100 = 10000 l increase by 18 % = 118 b decrease by 16 % = 84 118 * 84 = 9912 0.88 % decrease answer : b"
multiply(divide(subtract(multiply(add(const_100, 18), subtract(const_100, 16)), multiply(const_100, const_100)), multiply(const_100, const_100)), const_100)
