Hello!
To solve this we will use the Pythagorean Theorem, which is a²+b²=c², where a and b represent the legs and c represents the hypotenuse. We add up the squares of the legs and find the square root of our answer to find the length of the hypotenuse.
144+324=468
√468≈21.63
Therefore, the length of the hypotenuse is 21.63.
I hope this helps!
