Solution

## The correct option is B ₹ 1200The place to be fenced in a rectangular field is the outer boundary of the field, which is the perimeter of the rectangular field. So, length of fence required = perimeter of the rectangular field We know that perimeter of a rectangle = 2 (length + breadth) Therefore, length of the fence required = 2 x (length + breadth) = 2 x (150 +50) = 2 x 200 = 400 m The cost of fencing = ₹ 3 per metre (given) So, the total cost of fencing = Cost of fencing per metre x total length of the fence required = 3 x 400 = ₹ 1200  Suggest Corrections  0      Similar questions  Related Videos   Perimeter
