Question

A rectangular piece of land measures 0.5 km by 0.25 km. Each side is to be fenced with 4 rounds of wire. What is the length of the wire needed?

Answer 1

Each side should be fenced with four rounds of wire.

∴ length of wire required =4× perimeter of land

perimeter of land =2(l+b)=2(0.7+0.5)

=2.4km

∴ length of wire required =4×2.4=9.6km

∴9.6km length of wire is required to lay 4 rounds of fence.

Answer 2

Answer:

Each side should be fenced with four rounds of wire.

∴ length of wire required =4× perimeter of land

perimeter of land =2(l+b)=2(0.7+0.5)

                                                 =2.4km

∴ length of wire required =4×2.4=9.6km

∴9.6km length of wire is required to lay 4 rounds of fence.
