Question

What is the length of the hypotenuse in the given figure?

• A. 6 units
• B. 5 units
• C. 3 units
• D. 4 units

Answer 1

The correct option is B 5 units

Triangle $ABC$ is a right triangle, right-angled at $B$. So, AC is the hypotenuse.
Therefore, using the distance formula,
$A{C}^2=(5-1{)}^2+(1-4{)}^2$
$=16+9$
$A{C}^2=25$
$AC=5$ units
