Question

Consider a right-angled triangle with length of sides a, b and c. If a = 3 cm, b = 4 cm, then find the value of hypotenuse c?

• A. 10 cm
• B. 5 cm
• C. 25 cm
• D. 20 cm

Answer 1

The correct option is B 5 cm

If a and b are sides of length 3 cm and 4 cm then the value of hypotenuse, c can be found out by
$c^2=a^2+b^2$
$c^2=3^2+4^2$
$c^2=25$
$c=\sqrt{25}$
$c=5cm$
