by 0.5 km. Each side is to be fenced with 4
rows of wires. What is the length of the wire
needed? pls answer fast, who will answer
first I will mark the brainliest answer and like
his/her answer​​

Answer 1

Step-by-step explanation:

Since the 4 rows of wires are needed. Therefore the total length of wires is equal to 4 times the perimeter of rectangle. Perimeter of field

= 2 x (length + breadth)

= 2 x (0.7 + 0.5) = 2 x 1.2

= 2.4 km

= 2.4 x 1000 m

= 2400 m

Thus, the length of wire = 4 x 2400 = 9600 m = 9.6km
