#### Other Areas

Cut the figure into pieces, find the area of each, and add. If you're asked to find the area of a figure with a piece cut out of it, find the area of the whole figure, find the area of the piece, and subtract.

#### Other Perimeters

For any perimeter, just add the outside lengths all the way around.

#### Practice

1. Find the area of a circle with a diameter of 6.
1. 36π
2. 24π
3. 16π
2. What is the area of the triangle above?
1. 48
2. 9
3. 12
4. 18
5. 24
3. A box measured 5" wide, long, and 4" high. How many one-inch cube candies could fit in the box?
1. 10
2. 60
3. 90
4. 120
5. 150

1. d. If the diameter is 6, the radius is 3. A = π(3)2= 9π.
2. c. 8 is the base, b, and 3 is the height, h. × 8 × 3 = 12.
3. d. Since foot = 6 inches: 6 × 4 × 5 = 120 cubic inches. The candies measure 1 cubic inch each, so 120 of them will in the box.
