Question
The ratio of length to breadth of a rectangle is 4:3
respectively. Perimeter of rectangle is 84 m. If each side of a square is 33.33% less than the breadth of rectangle then What will be the difference between the areas of rectangle and square.Solution
Let the length of rectangle = 4x Then, breadth will be = 3x 2(l+b) = 84 2(4x + 3x) = 84 x = 6 then, the Length will be = 24 m then, the Breadth will be = 18 m Area of rectangle = 24 x 18 = 432m2 Side of square = (2/3) x 18 = 12m Area of square = 144m2 Hence, the Required difference is = (432 – 144) = 288m2
