Question

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

Answer 1

Answer:

1.4

Step-by-step explanation:

0.7 x 0.5 = 0.35     (this is the length of wire needed for 1 row of wire)

0.35 x 4 = 1.4          (Answer!)

Answer 2

ANSWER:-

length of wire needed = the perimeter of land

as we know perimeter of rectangle = 2(l+b)

now 0.7 km=700m and 0.5 km = 500m

now perimeter = 2(700+500)

= 2(1200)

= 2400m

but we have to fence four rounds so the wire needed= 2400*4 = 9600m or 9.6 km

so the answer is 9600m or 9.6 km
