1. 0-8: Area

2. 0-8: Area
Area: the number of square units needed to cover a surface. Area is measured in square units.

3. 0-8: Area

4. 0-8: Area Example 1: Find the area of each figure
A) A rectangle with a length of 7 yards and a width of 1 yard
A = lw
= (7)(1)
= 7
The area is 7 square yards

5. 0-8: Area Example 1: Find the area of each figure
B) A square with a side length of 2 meters
A = s2
= (2)2
= 4
The area is 4 square meters

6. 0-8: Area Example 1: Find the area of each figure
C) A parallelogram with a base of 11 feet and a height of 9 feet
A = bh
= (11)(9)
= 99
The area is 99 square feet

7. 0-8: Area Example 1: Find the area of each figure
D) A triangle with a base of 12 millimeters and a height of 5 millimeters
A = ½bh
= ½(12)(5)
= 30
The area is 30 square millimeters

8. 0-8: Area The formula for the area of a circle is A = πr2
Example 2: Find each area to the nearest tenth
A) The radius is 3 cm
A = πr2
= π(3)2
≈ 28.3
The area is about 28.3 square centimeters

9. 0-8: Area The formula for the area of a circle is A = πr2
Example 2: Find each area to the nearest tenth
A) The diameter is 21 m
A = πr2
= π(10.5)2
≈ 346.4
The area is about square meters
