The perimeter of a rectangle to that of a square is in the ratio of 11:6. If the square has an area of 144 square m and the length and breadth of the rectangle are in the ratio of 6:5, find the length and breadth of the rectangle.

Solution

Perimeter

(6 + 6 + 5 + 5) units ----- 88 m

22 units ----- 88 m

1 unit ----- 88m divided by 22 = 4 m

(Length) 6 units ----- 6 x 4 m = 24 m

(Breadth) 5 units ----- 5 x 4 m = 20 m

Answer: Length = 24 m; Breadth = 20 m
