Length of the hypotenuse is $5.831$

#### Explanation:

The question state that

"The legs of a right triangle are 3 units and 5 units. What is the length of the hypotenuse?"

From this it is apparent (a) that it is a right angle and (b) the legs form right angle and are not hypotenuse.

Hence using Pythagoras Theorem hypotenuse is

$\sqrt{{5}^{2} + {3}^{2}} = \sqrt{25 + 9} = \sqrt{34} = 5.831$
