ABCD is a parallelogram. Find the area and perimeter of each figure below.

 a.   A right slanting parallelogram, with  vertices, starting in the upper left corner and going clockwise, labeled, A, B, C, d. Side, B C, labeled, 41 inches. Side, D C, labeled, 57 inches. A dashed line, perpendicular side, A B, labeled 36 inches.

The formula to find the area of a parallelogram is (base)(height).

In a parallelogram, opposite sides will have equal length.



   b.  Right triangle labeled as follows: Vertical leg, 73 cm, horizontal leg, 56 cm, hypotenuse, 92 cm.

The formula to find the area of a triangle is 

Since this is a right triangle, you can use one of the legs for the height and the other for the base.
Find the perimeter by finding the sum of the given side lengths.
