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.
Answer & explanation
Correct answer: option 2
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
