Answer 2

The perimeter of the field is 1600 m.

Step-by-step explanation:

As given in question that the area of the square shaped field is 16 hectare.

we have to find the perimeter of the field in meter.

In this case, first of all we need to find the side (a) of square shaped field.

We know that,

Area of square = $a^{2}$

16 = $a^{2}$

16 x 10000 = $a^{2}$               ∵ 1 hectare = 10000 $m^{2}$

$\sqrt{160000} = a$

a = 400 m

Now,

Perimeter of square = 4 x a

                                  = 4 x 400

                                  = 1600 m

Hence the perimeter of the field will be 1600 m.
