Solution

The correct option is C

₹ 640


The rectangular plots together form a square of side 40 m.

Perimeter of the square thus formed
= 4 × side length
= 4 × 40
= 160 m

Now, cost of fencing the plots (excluding the common boundary)
= perimeter of the square × cost of fencing one metre length
= 160 × 4
= ₹ 640
