The short sides cannot be 7, because then you would have a base of 14, and a height of zero. (The two 7" sides would lie down flat on the base.)

Remember that any side must be less than the sum of the other two sides.

So, the base must be 7 and the two equal sides are 14. A tall thin triangle.

So, the 3rd side is 14.
