The area of a square field is 169$$m^2$$​. Its perimeter (in m) is:

Correct option is B

Given:

Area of square field = 169$$m^2$$​​

Formula Used:

Area  of a square =$$a^2$$​​

Perimeter of square = 4a

Where a is the side of square

Solution:

Area =$$a^2$$​= 169

​$$a= \sqrt{169}$$​​

a = 13m

Perimeter = 4a = $$4\times 13$$​ = 52m
