Some questions and their alternative answers are given. Select the correct alternative.

Height and base of a right angled triangle are 24 cm and 18 cm find the length of its hypotenuse


By Pythagoras theorem


(Hypotenuse)2 = (base)2 + (Perpendicular)2


Given,


Base = 18 cm


Perpendicular = Height = 24 cm


⇒ Hypotenuse2 = 242 + 182


⇒ Hypotenuse2 = 576 + 324


⇒ Hypotenuse2 = 900


⇒ Hypotenuse = 30 cm
