Answer:
190 sqft
Explanation:
Okay, let's break it down. There are a few ways to solve this, but i found that this was the easiest.
Multiply the area of a normal rectangle, 10ft and 25ft. We are left with 250. Now, as there are two major chunks, you can subtract the 4ft left over from the 10ft in all, giving us 6ft in length. Multiply the sides of the chunks (six feet) by the top portion (five feet), leaving us with 30. Since there are two chunks, multiply by two. We take the 60 feet and subtract it from the 250, leaving us with 190.
This should help!
