Question

What is the length of the hypotenuse of a right triangle if each of the two legs is 4 units? Square root of 8 units 4 units Square root of 32 units 8 units

Answer 1

The answer would be √32 or 4√2 (which is simplified) because of pythagoras' theorem. If we substitute a = b = 4 into it, then c must equal the root of 16 + 16, or 32. 

Answer 2

Answer:

The correct answer is √32

Step-by-step explanation:

Consider the provided information.

According to the Pythagoras theorem.

$a^2+b^2=c^2$

Where a and b are the legs of the right angle triangle and c is the hypotenuse.

Now it is given that the two legs are 4 unit. Substitute the value of legs in the above formula.

$4^2+4^2=c^2$

$16+16=c^2$

$32=c^2$

$\pm \sqrt{32}=c$

Ignore the negative value as length can not be a negative number.

$\sqrt{32}=c$

Hence, the correct answer is √32.
