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.
    A 5:9 Correct Answer Incorrect Answer
    B 3:4 Correct Answer Incorrect Answer
    C 4:7 Correct Answer Incorrect Answer
    D 7:8 Correct Answer Incorrect Answer
    E 2:5 Correct Answer Incorrect Answer

    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
