pls say me the answer of this question as soon as possible​

Answer 1

length of side of square field is 20m

Step-by-step explanation:

let the side of the square field is a.

let the perimeter of the field is b

perimeter of a square = 4a

cost of fencing per m² = 30

cost of fencing b metres = 2400

perimeter of the square field is:

$b = \frac{2400}{30}$

$b = 80$

since, b is the perimeter of the square

b = 4a.

$4a = 80$

$a = 20$
