6. A rectangular piece of land measures 0.7 km by
Bess [88]

Answer:

9.6km / 9600m

Step-by-step 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.
