Question

A farmer wants to fence his field by a wire. Length and breadth of his field is 20 m and 16m respectively. How much wire would be needed to fence the whole field. What will be the cost of fencing the field, if the rate of fencing the wire is 3 per metre?

Answer 1

hey mate here is your answer

length of a field. = 20m
breadth of a field. = 16m
perimeter of a field = 2×(l+b)
= 2×(20+16)
= 2×36
= 72m
cost of fencing = 72×3
= 216 ruppes

i hope this helps you

thank you ❤ ❤

Answer 2

Given:
length- 20m
breadth- 16m
cost of fencing- ₹3 /m

1. the length of the wire needed for fencing= perimeter of the field
= 20×2 + 16×2
=72meters

2. total cost of fencing:
- length of wire × cost of fencing per metre
= (72 × 3)/-
= ₹216
