1. Perimeter and Area of Rectangles Kaitlyn Geary

2. Definitions Perimeter: the border or outside boundary of a two dimensional figure Area: the quantitative measure of a plane or curved surface; two-dimensional extent Reference: dictionary.com

3. Calculating Perimeter Perimeter = 2 * Length + 2 * Width Example: P = 2(L) + 2(W) = 2(4) + 2(2) = 12 units 4 2

4. Calculating Area Area = Length * Width Example: A = L * W = 4 * 2 = 8 units squared 4 2

5. Example Problem Calculate the perimeter and area of the following figure: 9 5

6. Example Solution P = 2(L) + 2(W) = 2(9) + 2(5) = 28 units A = L * W = 9 * 5 = 45 units squared
