Question

A square wrestling mat has a perimeter of 12x + 32 feet. Write an expression that represents the side length of the mat in feet.

Answer 1

Answer: $3x+8\ ft$

Step-by-step explanation:

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

$\Rightarrow 4a=12x+32\\\\\Rightarrow a=\dfrac{12x+32}{4}\\\\\Rightarrow a=3x+8\ ft$

Therefore, the side length of the square mat is $3x+8\ ft$
