to enclose the square lot, you need to have its perimeter.

the perimeter of a square is defined by the formula:

P = 4s

where P is the perimeter and s is the length of 1 side


you are given that the length of 1 side is (5x-3).

Substituting you'll have:

P = 4 (5x-3)

P = 20x - 12


Therefore you'll need (20x-12) meters of fencing materials
