You can put this solution on YOUR website!
A right triangle would give you the maximum area.
Assume 10 is the base, the maximum height you could have is 7, when it's a right triangle.
Any other angle, would reduce the height while maintaining the leg length at 7.
So,
A%5Bmax%5D=%281%2F2%29%287%29%2810%29=35
