1-106.

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

1. Write an equation to represent this information.

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

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

2. Solve for $x$.

$x=2$

3. What is the area of the square?

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