  1. Objective: Students will find the area of parallelograms (10-1).

  2. Vocabulary • Base – any one of the sides of a parallelogram • Height – the shortest distance from the base to the opposite side. • Area of a parallelogram– A = bh

  3. Steps: • Read directions and copy problem. • Use the following formula A= bh • Plug in your #’s. • Multiply.

  4. Examples Find the area of each parallelogram to the nearest tenth. 8 5

  5. Examples Find the area of each parallelogram to the nearest tenth. A = bh 8 5

  6. Examples Find the area of each parallelogram to the nearest tenth. A = bh A = 5 x 8 8 5

  7. Examples Find the area of each parallelogram to the nearest tenth. A = bh A = 5 x 8 A = 40 The area is 40 square units. 8 5

  8. Examples Find the area of each parallelogram to the nearest tenth. 16.2m 3.7m

  9. Examples Find the area of each parallelogram to the nearest tenth. A = bh 16.2m 3.7m

  10. Examples Find the area of each parallelogram to the nearest tenth. A = bh A = 3.7 x 16.2 16.2m 3.7m

  11. Examples Find the area of each parallelogram to the nearest tenth. A = bh A = 3.7 x 16.2 A = 59.94 The area is 59.9 square meters. 16.2m 3.7m

  12. Examples • A company in Dallas, Texas makes ceramic tile that is used to cover floors or walls. Find the area of a ceramic tile that needs to be glazed if it is shaped like a parallelogram with the height of 4 ½ inches and a base of 6 ¾ inches. Use the formula for the area of a parallelogram to find the area of the top of the tile.

Find the area of a ceramic tile that needs to be glazed if it is shaped like a parallelogram with the height of 4 ½ inches and a base of 6 ¾ inches. Use the formula for the area of a parallelogram to find the area of the top of the tile. A = bh A = 6 ¾ x 4 ½ replace b with 6 ¾ and h with 4 ½

  15. A company is Dallas, Texas makes ceramic tile that is used to cover floors or walls. Find the area of a ceramic tile that needs to be glazed if it is shaped like a parallelogram with the height of 4 ½ inches and a base of 6 ¾ inches. Use the formula for the area of a parallelogram to find the area of the top of the tile. A = bh A = 6 ¾ x 4 ½ replace b with 6 ¾ and h with 4 ½ A = 27/4 x 9/2 6 ¾ = 27/4 and 4 ½ = 9/2

Find the area of a ceramic tile that needs to be glazed if it is shaped like a parallelogram with the height of 4 ½ inches and a base of 6 ¾ inches. Use the formula for the area of a parallelogram to find the area of the top of the tile. A = bh A = 6 ¾ x 4 ½ replace b with 6 ¾ and h with 4 ½ A = 27/4 x 9/2 6 ¾ = 27/4 and 4 ½ = 9/2 A = 243/8 or 30 3/8 The area of the tile is 30 3/8 square inches.

  17. Guided Practice Find the area of each parallelogram to the nearest tenth. 6 4.4m 8 3.1m

  18. Guided Practice Find the area of each parallelogram to the nearest tenth. A = bh A = bh A = 6 x 6 A = 3.1 x 4.4 A = 48 square units A = 13.6 m² 6 4.4m 8 3.1m
