hope it will help you

Answer 2

Answer:

3cm , 4cm, 5cm the answer

Explanation:

Pythagorean triplet: Square of hypotenuse side(highest side) is equal to sum of squares of other two sides.

1) 2cm, 4cm, 5cm

${2}^{2} + {4}^{2} = {5}^{2} \\ \\ 4 + 16 = 25 \\ \\ 20 \neq25$

So, It is not a Pythagorean triplet

2) 2cm, 6cm, 7cm

${2}^{2} + {6}^{2} = {7}^{2} \\ \\ 4 + 36 = 49 \\ \\ 40 \neq49$

So, it is also not a Pythagorean triplet

3) 3cm, 4cm, 5cm

${3}^{2} + {4}^{2} = {5}^{2} \\ \\ 9 + 16 = 25 \\ \\ 25 = 25$

It is a Pythagorean triplet.

${ \therefore{ \sf{3cm, 4cm, 5cm \: is \: the \: answer}}}$
