the length and breadth of a rectangle is increased by 10 % and 25 % respectively . what is the increase in the area ?
explanation : 100 * 100 = 10000 110 * 125 = 13750 - - - - - - - - - - - 3750 10000 - - - - - - 3750 100 - - - - - - - ? = > 37.5 % answer : option b
divide(multiply(subtract(rectangle_area(add(10, const_100), add(25, const_100)), rectangle_area(const_100, const_100)), const_100), rectangle_area(const_100, const_100))
