Question

find the cost of fencing a rectangular field of side 42 m by 30 M if the cost of wire is rupees 35 per metre and labour cost is rupees 850​

Answer 1

Answer:

Perimeter of a rectangle = 2(l+b)

2(42+30)

2(72)

= 144m

Cost for wire = 144 * 35

= 5040 Rs

Cost for labour = 144 * 850

=122400 Rs

Total Cost = 5040 + 122400 = 127,440 Rs
