3-88.

The perimeter is the distance around a shape.

Label the values of all the sides.

Add these values together to find the expression for the perimeter.

*x* + *x* + (*x* − 2) + *x* + 1 + 1 + 1 + 1 + *x* + *x*

Simplify this expression by combining like terms.

The area is the space bound within the perimeter.

Add the areas of all 4 tiles within the perimeter.

*x*^{2} + *x* + *x* + 1

Now simplify this expression.

P = 6*x* + 2
