Given
Square wrestling has a perimeter of 12x+32 feet
Suppose the side of the square mat is a
Perimeter is the sum of the side lengths of a polygon
for square, it is given by
[tex]\Rightarrow 4a=12x+32\\\\\Rightarrow a=\dfrac{12x+32}{4}\\\\\Rightarrow a=3x+8\ ft[/tex]
Therefore, the side length of the square mat is [tex]3x+8\ ft[/tex]
