Question

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?

Answer 1

$a^{2}+ b^{2} = c^{2}$ that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.' 
$25^{2}+ 60^{2}= x^{2}$
625+3600=$x^{2}$
4225=$x^{2}$
Therefore,
$\sqrt{4225}$=x
65=x
The length of the hypotenuse is B.65 centimetres.
