### 10-1 - Area of a Parallelogram

1. 1. 10.1 – Area of a Parallelogram Joseph Williams Melvin E. Sine Elementary [email_address] Objective: Find the area of a parallelogram.
2. 2. Vocabulary Base of a parallelogram – p. 476 – length of any of its sides. Height of a parallelogram – p. 476 – the perpendicular distance between the side whose length is the base and the opposite side. Perpendicular – p. 476 – two lines are perpendicular if they meet at a right angle.
3. 3. Finding Area A = bh area = base times height Base, b Height, h = 5m = 8m 8 x 5 = 40 m squared
4. 4. Your Turn 4 m 10 m 20 m 25 m 4 x 10 = 40 m squared 25 x 20 500 m squared
5. 5. Your Turn b = 15 m A = 60 m squared What is the height of this parallelogram? 60 / 15 = 4 m
