Answer:
35ft
Step-by-step explanation:
It's easiest to split the shape into two sections.
The bottom rectangle is 4ft x 5ft = 20ft
The upper rectangle is 3ft x 5ft = 15ft. The reason why it is not 3ft by 9ft is because I subtracted 4 from 9 because I did not use the full side length.
Then 20ft + 15ft = 35ft
