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.
