Question

5. A rectangular piece of land measures 0.7 km by 0.5 km. Each side is to be
fenced with 4 rows of wires. What is the length of the wire needed?​

Answer 1

Answer:

Dimensions of land = 0.7 km x 0.5 km

Perimeter of the land would be = 2 ( 0.7 + 0.5 ) km

                                                    = 2.4 km

If it is fenced with four rows of wires then length of wire needed,

= 4 x 2.4 km

= 9.6 km

Hence, 9.6 km of wire is needed to fence it.
