Question

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

3
3 √2
√41

Answer 1

√41 units

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

Answer 2

Using Pythagoras' theorem

hyp²= side²+side²

hyp²= 4²+5²

hyp²= 16+25

hyp= 41

hyp= √41

hyp= 6.40

Therefore the length of the hypotenuse is √41.
