a rectangle having length 89 cm and width 34 cm . if the length of the rectangle is increased by eighty percent then how much percent the breadth should be decreased so as to maintain the same area .
"explanation : solution : ( 80 / ( 89 + 80 ) * 100 ) % = 47.33 % answer : c"
multiply(add(const_1, divide(divide(multiply(89, 34), add(89, divide(multiply(multiply(const_3, const_10), 89), const_100))), 34)), const_10)
