Question

A rectangular piece of land measures 0.8 km by 0.6 km.each side is to be fenced with four rows of wires.what is the length of the wire needed?

Answer 1

Answer:

Length =0.8km

Breadth =0.6km

perimeter=2(L+B)

=2×1.4km

=2.8km

each side is fenced with 4 rows of wire

Length of wire=4×2.8km

11.2km

Answer 2

Answer:

11.2 km or 11200 m

Step-by-step explanation:

0.8km=800m

0.6km=600m

Find perimeter first. So the formula is 2*(l+b)

=2*(800+600)

=2*(1400)

=2800m or 2.8km

Now we need to multiply to find the length.

=4*2800

=11200m or 11.2km
