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.

Answer:
63 m
Step-by-step explanation:
Perimeter is 276, 2L + 2W = 276, so L + W = 138
L = 75
