1. Calculating Perimeter and Area
Adapted from Walch Education

2. Sometimes we need to calculate the perimeter or distance around a polygon (a two-dimensional figure formed by three or more segments), as well as find the area or the amount of space inside the boundary of a polygon.

3. The distance formula is a valuable tool for both of these calculations .

4. Perimeter is the sum of the lengths of all the sides of a polygon.
The area of a triangle is found using the formula

5. Calculating the Perimeter of a Polygon
Calculate the length of each side of the polygon using the distance formula:
Add all the lengths of the polygon to find the perimeter.
Simplify and approximate the value if necessary.
The final answer must include the appropriate
label (units, feet, inches, meters, centimeters, etc.).

6. Calculating the Area of a Rectangle
Calculate the length of the base of the rectangle using the distance formula:
Calculate the length of the height of the rectangle using the distance formula:
Calculate the area using the formula
Area = (base)(height)

7. Remember…
The final answer must include the appropriate label (units2, feet2, inches2, meters2, centimeters2, etc.). We will discuss Calculating the Area of a Triangle in class 
