Answer 1

Answer:

320 m

Step-by-step explanation:

According to the question

The side of the square field, a = 20 m

We are to find the length of the wire required to fence.

In this case, we need to the find the perimeter of the square.

We know that,

Perimeter of the square, P = 4a

= 4 x 20

= 80 m

we need them to fencing the square four times.

The required length = 4P

= 4 x 80

= 320 m

Hence the required length of the fence is 320 m.

Answer 2

Answer:

0.04 hectares

Step-by-step explanation:

Area of square field = Side x Side

= 20x20

= 400m²

= 400/ 10000

= 0.04 hectare
