Find the area and perimeter of the trapezoid at right.  

Separate the trapezoid into separate figures: a right triangle at left, a rectangle in the middle, and a right triangle at right.

Vertical segments drawn from top vertices, perpendicular to the bottom base, creating shaded right triangles on right & left of trapezoid.

Label the height of each triangle, . For the left triangle, label the second leg, . Solve for  and .

Labels added to each vertical segment, h, and base of left shaded triangle, a.


Follow a similar process for the second triangle.

Labels added to right shaded triangle, e on the hypotenuse, d on the base.
