Question

How long is the hypotenuse of a right triangle if its legs are 3 feet and 4 feet long?

• A. 25 Feet
• B. 1 Foot
• C. 7 Feet
• D. 5 Feet

Answer 1

The correct option is D 5 Feet

According to Pythagoras theorem, $h^2=a^2+b^2$
So, $h^2=3^2+4^2$
$h^2=9+16$
$h^2=25$
h = 5
Therefore hypotenuse of the right triangle is 5 feet long.
