Answer 2

Answer:

Option A) 5 cm,12 cm,13 cm is the correct answer

As We know

Pythagoras theorem

=a²+b²=c²

where c=Hypotenuse

and a&b=other sides

here

If 5²+12²=13²

then it's correct

5²+12²=13²

25+144=169

169=169

L.H.S=R.H.S

hence verified

Therefore it's a right triangle with Hypotenuse 13 cm

But it won't work in C & D

because their adjacent sides/side are/is longer than Hypotenuse,but Pythagoras theorem states that Hypotenuse is the longest side

and in B) 7²+5² doesn't equals 11²
