calculate the effect changes in dimension of a rectangle will have on its area , if length is increased by 15 % and its breadth is decreased by 10 % ?
"let l and b be 100 each 100 * 100 = 10000 l increase by 15 % = 115 b decrease by 10 % = 90 115 * 90 = 10350 3.5 percent increase answer : e"
multiply(divide(subtract(multiply(add(const_100, 15), subtract(const_100, 10)), multiply(const_100, const_100)), multiply(const_100, const_100)), const_100)
