Question

The cost of fencing a rectangular field 34 m long and 18 m wide at Rs 22.50 per metre is
(a) Rs 2430
(b) Rs 2340
(c) Rs 2400
(d) Rs 3340

Answer 1

(b) Rs 2340
Perimeter of the rectangular field = 2(Length + Breadth)
= 2(34 + 18) m = 104 m
Cost of fencing 1 metre = Rs 22.50
Cost of fencing 104 m = Rs (22.50$\times$104) = Rs 2340
