Question:

The perimeter of a rectangular field is 480 m. The ratio between the length and the breadth of the field is 2 : 1. Find the area of the field.

Options:

12,400 m2

12,800 m2

12,850 m2

13,800 m2

Correct Answer:

12,800 m2

Explanation:

The correct answer is Option (2) → 12,800 m2

 

Length be, L and Breadth be, B

Perimeter = 2L + 2B = 480

L+B = 240

Also, L : B :: 2 : 1

L = 2B

Thus, 2B+B = 3B = 240

B = 80

L = 160

Area of the field = LB = 160 × 80 = 12800
