We find the perimeter by adding all the sides
in the shape.
Side 1: 7t - 8
Side 2: 9t - 10
Side 3: 10t + 1
Side 4: 5t + 4
(7t - 8) + (9t - 10) + (10t + 1) + (5t + 2) = the perimeter.
Simplify, and we can know that the answer is 31t - 15!
Hope this helps! Please tell me if I did anything wrong, thank you and have a great day =D
