Answer:
A
Explanation:
First find the length of the base of the triangle.
Use Pyth theorem: 100^2 + 100^2 = c^2
10,000 + 10,000 = c^2
20,000 = c^2
141.42 = length of side against the house
Subtract the 100 ft that the house covers, and you need 41.42
Add that to 100 + 100 + 41.42 = 241.42 or 241 ft
