the length and breadth of a rectangle is increased by 30 % and 45 % respectively . what is the increase in the area ?
"100 * 100 = 10000 130 * 145 = 18850 - - - - - - - - - - - 8850 10000 - - - - 8850 100 - - - - - 88.50 answer e"
divide(multiply(subtract(rectangle_area(add(30, const_100), add(45, const_100)), rectangle_area(const_100, const_100)), const_100), rectangle_area(const_100, const_100))
