take the side of length 7. If you ‘connect’ that side to the side with length 10, you can add another side to make a triangle, right?
Well if you think about it, the maximum area will occur when the 7 side and the 10 side are at right-angles.

So using the formula for area of a triangle:
A = 1/2bh

The area would be:
A = 1/2(7)(10)
A = 35

So C.
