Answer:
276 ft
Explanation:
So to find the area, it just means multiply the numbers together.
First you would do the base times 10.
The base = 6 ft so 6*10 would be 60.
Then you multiply the 12 ft and 18 ft together.
You would get 216 ft.
Last, you would add the 2 answers together.
216 + 60 would equal 276.
