Perimeter and Area of Polygons

Lesson 1

Problem:	What is the area of a parallelogram with base 18 mm, side length 12 mm, and height 5 mm?
Solution Step 1:	Area of parallelogram = Base x perpendicular height Base = 18 mm Perpendicular height = 5 mm
Solution Step 2:	Area of parallelogram = Base x perpendicular height                                          = 18 mm x 5 mm                                          = 90 sq mm

Try two practice problems:

 A.

What is the perimeter of a parallelogram with base 26 cm, side length 71 cm, and height 31 cm?

B.  

What is the area of a parallelogram with base 34 mm, side length 72 mm, and height 19 mm?
