The length of the other leg is 5cm

By Pythagoras theorem we know that
$hypotenuse^2$ = $Perpendicular^2$ + $base^2$

Putting the values you will get
Other leg= $sqrt(13^2-12^2)$ =5cm
Hope this answer helps 😁

$5$

Using the Pythagorean Theorem, the square of the hypotenuse is equal to the sum of the squares of the sides.

$h^2 = a^2 + b^2$
$13^2 = 12^2 + b^2$
$169 - 144 = b^2$ ; $25 = b^2$ ; $b= 5$
