Area of Parallelograms Lesson 11-4

Area of Parallelograms In the Activity we found that the area of a parallelogram is similar to the area of a rectangle. The area of a rectangle is l x w

Parallelogram h b Find the area of a parallelogram A = bh Remember the units when finding area of any figure are always SQUARED!!

12cm 15cm A = bh A = 15cm x 12cm A = 180 cm ² Find the area of the figure round to the nearest tenth if necessary.

0.75m 1.5m A = bh A = 1.5m x 0.75m A = 1.1 m ² Find the area of the figure round to the nearest tenth if necessary.

2yd 3 ½ yd A = bh A = 3 ½ yd x 2 yd A = 7 yd² Find the area of the figure round to the nearest tenth if necessary.

7.9cm 7.2cm A = bh A = 7.2cm x 7.9cm A = 56.9 cm ² Find the area of the figure round to the nearest tenth if necessary.
