Question

Karan wants to fence his square field on all the sides. Calculate the total cost of the fence if the cost of fencing the field is ₹ 10 per metre.

• A. ₹ 140
• B. ₹ 210
• C. ₹ 230
• D. ₹ 280

Answer 1

The correct option is D ₹ 280

To find out the total cost of the fence, first of all, we have to find the length of the field that has to be fenced.

So, the length of the field that has to be fenced
= Perimeter of the square field
= 4 x side
= 4 x 7 = 28 m

So, the total cost of the fence
= Length of fence(in m) x rate of fencing (per m)
= 28 m $\times$ ₹ 10/m
= ₹ 280
