Answer:
It's 10 ft.
Step-by-step explanation:
When they ask for the perimeter, you know to "add" the sq ft, or the ft.
(ex: if i had a triangle, gave you 3 numbers such as 11 ft, 11 ft, and 14 ft, then asked you what the perimeter would be, you'd add 11, 11, and 14 together and get 36 (ft.)
So we had 4 numbers: 2ft, 3ft, 1ft, 4ft. add them all and it's 10ft.
