Question

Mr.ammad wants to fence the boundaries of his house but he is not sure how much fencing wire should he buy if he wants to put a double layer of wires . (the dimensions of his house are 177m*102m) also state how much it would cost him if a single metre of wire costs rs.10

Answer 1

He needs 1,116 m of wire. If a meter of wire costs $10, then the total wiring will cost $11,160.

Explanation:

Since he wants to double layer the fencing of his house, he'll need at least two times the length of the perimeter of his house in wires. Since his house has a rectangular shape, it's perimeter is given by the following formula:

perimeter = 2*length + 2*width

perimeter = 2*177 + 2*102 = 354 + 204 = 558 m

wire = 2*perimeter = 2*558 = 1116 m

He needs 1116 m of wire.

If each meter of wire costs $10, then the whole wiring will cost:

total cost = wire*10 = 1116*10 = $11,160
