Hard
In a right triangle, the two legs measure 24 cm and 45 cm. Find the length of the hypotenuse.
Explanation
Explanation
By the Pythagoras theorem, (hypotenuse)² = (leg₁)² + (leg₂)². Here 24² + 45² = 576 + 2025 = 2601 = 51², confirming the sides 24, 45, 51 form a right triangle so the hypotenuse is 51 cm.
PRO TIP
Re-check your working by substituting the answer back into the original question.
