sqrt(170), or 13.0384...

Explanation:

You know that the Pythagorean Theorem is:

a^2+b^2=c^2,
Where:
a is the length of one of the legs,
b is the length of the other leg, and
c is the length of the hypotenuse.

You know the lengths of the two legs are 7 and 11, so we'll say that a is 7, and b is 11.

Knowing that, we can plug those into our equation and simplify like so:

7^2+11^2=c^2
49+121=c^2
170=c^2
sqrt(170)=c=13.0384...

Hope this helped!
