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
