Finding the perimeter
Finding the perimeter of a shape means that you are looking for the
distance around the outside of that shape.
Example #1
Find the distance around for the following irregular polygon
Distance around = 5 inches + 4 inches + 2 inches + 3 inches + 6 inches = 20 inches
Example #2
Find the distance around for the following trapezoid
Distance around = 5 inches + 8 inches + 4 inches + 3 inches = 20 inches
Example #3
Find the distance around the following triangle
Distance around = 5 inches + 4 inches + 2 inches = 11 inches
Example #4
Find the distance around the following rectangle
Distance around = 3 inches + 3 inches + 6 inches + 6 inches = 18 inches
Example #5
Find the distance around the following square
distance around = 5 inches + 5 inches + 5 inches + 5 inches = 20 inches
You can get the same answer by doing 4 × 5 = 20
