Hard
In a right triangle, the two legs measure 200 cm and 45 cm. Find the length of the hypotenuse.
Explanation
Explanation
By the Pythagoras theorem, (hypotenuse)² = (leg₁)² + (leg₂)². Here 200² + 45² = 40000 + 2025 = 42025 = 205², confirming the sides 200, 45, 205 form a right triangle so the hypotenuse is 205 cm.
PRO TIP
Re-check your working by substituting the answer back into the original question.
