Your question needs a correction,
Correct question : find the length of the hypotenuse of the right angled triangle , the other two sides of which measures 9 cm and 12 cm.
Solution :
As given that the given ∆ is a right angled ∆ , Pythagoras theorem can be applied.
By Pythagoras Theorem ,
( sum of squares of two sides except hypotenuse )² = hypotenuse²
= > ( 9 cm )² + ( 12 cm )² = hypotenuse²
= > 81 cm² + 144 cm² = hypotenuse²
= > 225 cm² = hypotenuse²
= > ±√ 225 cm² = hypotenuse
Sides can't negative.
= > 15 cm = hypotenuse
Hence, length of remaining side , other side and hypotenuse is 15 cm
