Question
If the area of a square is 144 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 the area of the square to the area of the rectangle.Solution
 Area of square = 144 cm², Side of square = 12 cm  Area of rectangle = (l x b)  Length = (12 x 1.5 = 18) cm  Breadth = (12 x 1.2 = 14.4) cm  Area of rectangle = (18 x 14.4 = 259.2) cm²  Required ratio = 144/259.2 = 5/9 = 5:9
