Answer 1

Step-by-step explanation:

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=302400

b = 80b=80

since, b is the perimeter of the square

b = 4a.

4a = 804a=80

a = 20a=20
