The length and breadth of a rectangular garden are in the ratio 3 : 2. If the perimeter of the garden is 120 m, find its area (in m2).

1. 968
2. 454
3. 144
4. 864

Correct answer: 864

Solution

Let length = 3x and breadth = 2x. Perimeter = 2(l + b) = 2(3x + 2x) = 10x = 120, so x = 12. Length = 36 m, breadth = 24 m. Area = 36 x 24 = 864 m2.
