Question

6. A rectangular piece of land measures 0.7 km by

of wire. What length of wire is needed ?
0.5 km. Each side is to be fenced with four rounds​

Answer 1

9.6km / 9600m

Explanation

B= 0.5km

L = 0.7km

perimeter of a rectangle = 2(L+B)

= 2( 0.7 + 0.5)

= 2.4km

wire for one round is 2.4km

wire for 4 rounds = 2.4 x 4

= 9.6km wire is required.

Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.
