Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

There is a right angled triangle, in which,

Perpendicular = 7 cm

Hypotenuse = 13 cm

Base = b cm

As we know the formula for "Pythagorus theorem":

[tex]H^2=B^2+P^2\\\\13^2=b^2+7^2\\\\169=b^2+49\\\\169-49=b^2\\\\b^2=120\\\\b=\sqrt{120}\ cm[/tex]

Hence, Option 'D' is correct.
