I got 280ft^2. I multiplied the areas by 2 because the opposite sides are equal.
We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.
According to picture longest side is 18
So this triangle must follow inequality
9+x>18
or 9-9+x>18-9
or x>9
that means value of x must be more than 9.
choices a, c, d are greater than 9 except choice b
Hence choice B-9 is the final answer.
