Solution

The correct option is C
24 cm

Let the length of the unknown side be $x$

Then $x^{2} + 7^{2} = 25^{2}$ ( By Pythagoras Theorem )

i.e $x^{2} + 49 = 625$

$\Rightarrow x^{2} = 625 - 49$

$\Rightarrow x^{2} = 576$

$\Rightarrow x = \sqrt{576}$

= 24 cm

Hence the length of the other side is 24 cm

The correct option is C 24 cm Let the length of the unknown side be x Then x2+72=252 ( By Pythagoras Theorem ) i.e x2+49=625 ⇒x2=625−49 ⇒x2=576 ⇒x=√576 = 24 cm Hence the length of the other side is 24 cm
