Question

Length and breadth of a rectangular field is 120 m and 80m it has to be fenced with 2 rounds of wine if the cost of the wine is₹5 per metre then the cost of fencing the field

Answer 1

Length of field=120m

Breadth of field=80m

Length of wire needed to be fenced=

2*perimeter=2*

Answer 2

Length = 120m
Breadth = 80m
Perimeter = 2(l+b) = 2(120+80) = 2×200 = 400 cm
Cost of fencing = Rs. 5 × 400 = Rs. 2000
Cost of fencing second round = Rs. 2000 × 2 = Rs. 4000
Thus, it would cost 4000 Rs. to fence wine.
