#10x+3#

Recall that the perimeter of a square is given by

#P=4S# where #S# represents the side length.

This means that

#S=P/4,# or the side length is one-fourth of the perimeter.

Here, #P=40x+12#, so, we see #4S=40x+12.#

Thus,

#S=(40x+12)/4=(40x)/4+12/4=10x+3#

#"side" = 10x+3#

Given that the perimeter is:

#"Perimeter"= 40x+12#

We know that, for a square, the #"Perimeter" = 4 xx "side"#

#4xx "side"= 40x+12#

Divide both sides of the equation by 4:

#"side"= 10x+3#
