Question

A square field of side 78m is to be fenced with barbed wire that has to go around the boundary 4 times. how much wire will be required? What will be the cost of fencing if the wire cost Rs.55 per meter and labour charged rs 2150

​

Answer 1

side = 78m

perimeter=4*side

4*78=312m

length of wire required=312*4=1248m

cost of fencing=1248*55=68640

cost charged by labour=1248*2150=2683200

total cost=2683200+68640=2751840rs. Not sure buddy
