  6. Example 4 Find the area of each rectangle.. 12 mi. 9 mi.

  7. FYI You can use the formula for the area of a rectangle to write a formula for the area of a parallelogram. Imagine cutting off the triangle drawn in the parallelogram and sliding it to the right to form a rectangle. The area of a parallelogram = bh. The area of a rectangle = lw. The base of the parallelogram is the length of the rectangle. The height of the parallelogram is the width of the rectangle.

  8. Example 5: Finding the Area of a Parallelogram Find the area of the parallelogram. 1 1 ft 4 1 2 ft 2

  9. Example 6 Find the area of each parallelogram. 8 ft 7 ft

  10. Example 7 Find the area of each parallelogram. 5.6 m 12 m
