The length of a side of a square is $5x + 2$ units. Assuming the perimeter is $48$ units, complete the following problems.

1. Write an equation to represent this information.

   Hint (a):

   To find the perimeter, add the side lengths. In this case we have a square which has four equal side lengths.

   Answer (a):

   One possibility is $4(5x + 2) = 48$.

2. Solve for $x$.

   Answer (b):

   $x = 2$

3. What is the area of the square?

• Hint (c):

  Remember to substitute $x = 2$ back into the original equation.
