6-81.

Label the missing sides. Notice that the shape is a rectangle with a 2 by 3 section removed.

To find the perimeter, add the value of each side. To find the area, multiply the base of the rectangle by the height and subtract the missing area.

Perimeter = 40 units
Area = 65 − 6 = 59 units2

To find the perimeter, add the values of all the sides. To find the area, recall how to find the area of a trapezoid, then subtract the missing 2 by 3 section.

Area of a trapezoid.

$\text{Area}=\left(\frac{1}{2}\right)(\text{base}_1+\text{base}_2)(\text{height})$
