(a) 13

(b) 12

(c) 5

(d) 169

The question was asked during an online interview.

This intriguing question comes from Pythagorean Triplet topic in portion Squares and Square Roots of Mathematics – Class 8

Answer 1

Right option is (a) 13

For explanation: Here the given triangle is a right angled triangle, we can use Pythagoras theorem. Theorem will help us find the length of side AC.

Using Pythagoras Theorem we get,

12^2+5^2= AC^2,

AC=13.
