a rectangle having length 140 cm and width 40 cm . if the length of the rectangle is increased by thirty percent then how much percent the breadth should be decreased so as to maintain the same area .
explanation : solution : ( 30 / ( 140 + 30 ) * 100 ) % = 17.64 % answer : a
multiply(add(const_1, divide(divide(multiply(140, 40), add(140, divide(multiply(multiply(const_3, const_10), 140), const_100))), 40)), const_10)
