The legs of a right triangle have lengths of 4 and 5 units. find the length of the hypotenuse.

3
3 √2
√41

√41 units

Step-by-step explanation:

If 'a' and 'b' are the legs of a triangle while 'c' is the hypotenuse,

Then by Pythagoras theorem, a² + b² = c²

By substituting in the values from the question:

⇒ (4 units)² + (5 units)² = c²

⇒ c² = 41 units²²

⇒ c = √41

Thus the length of the hypotenuse is √41 units
