Solution

The correct option is B
₹540

To find the cost of fencing we need to find the perimeter of the field.
Given,
Length=12, Breadth=15, Cost per meter = ₹10
Perimeter of Rectangle
=2 (Length + Breadth)
$= 2 \times (12 + 15)$
$= 2 \times (27)$
$= 54 m$

Cost of fencing
= (Perimeter) x (Cost per meter)
= 54 x 10
=₹ 540
