Question

Find the perimeter of the figure below. Notice that one side length is not given.

Assume that all intersecting sides meet at right angles.
Be sure to include the correct unit in your answer.

Answer 1

Perimeter of the given polygon = 48 ft

Explanation:

Perimeter of the given polygon = Sum of measures of all sides of the polygon

= AB + BC + CD + DE + EF + FA

= 9 + 7 + CD + 8 + 4 + 15

= 43 + CD

Since, CD = AB - EF

= 9 - 4

= 5 ft

Therefore, perimeter of the given polygon = 43 + 5

= 48 ft
