the length of a rectangle is halved , while its breadth is tripled . wa tis the % changein area ?
let original length = x and original breadth = y . original area = xy . new length = x . 2 new breadth = 3 y . new area = x x 3 y = 3 xy . 2 2 increase % = 1 xy x 1 x 100 % = 50 % . 2 xy c
multiply(divide(subtract(multiply(const_3, divide(const_1, const_2)), const_1), const_1), const_100)
