Question

Find the cost of fencing a rectangular field 25m long and 16m wide at Rs7.25 per metre.

Answer 1

Length of the rectangular field, l = 25 m

Breadth of the rectangular field, b = 16 m

Perimeter of the rectangular field = 2(l + b) = 2 (25 m + 16 m) = 2 × 41 m = 82 m

Given, Cost of fencing = Rs 7.25/ m

∴ Cost of fencing the rectangular field × Cost of fencing = 82 m × Rs 7.25/ m = Rs 594.50

Thus, the cost of fencing the rectangular field is Rs 594.50.
