Question
If the area of a square is 400 cm² and the breadth of a
rectangle is 20% more and the length is 50% more than the side of the square, then find the ratio of area of square to the area of rectangle.Solution
 Area of square = 400 cm², Side of square = 20 cm  Area of rectangle = (l x b)  Length = (20 x 1.5 = 30) cm  Breadth = (20 x 1.2 = 24) cm  Area of rectangle = (30 x 24 = 720) cm²  Required ratio = 400/720 = 5/9 = 5:9
