Answer: 2.83
Explanation:
For this question you have to use pythagoras' theorem.
Pythagoras' theorem states that:
c²=a²+b²
So first you put the numbers in:
c²=2²+2²
Then you would find out what 2² is:
2²=4
c²=4+4
c²=8
Then because you just want c (the Hypotenuse) on it's own you have to square root 8.
√8=2.83 (to the nearest hundredth)
Hope this helps :)
