Explanation:

- Length Calculation: The length of the rectangle is given as 5 times its breadth. Since the breadth is 10 cm, the length is $5\times 10=50$ cm.

- Perimeter Formula: The formula for the perimeter of a rectangle is $2\times (\text{Length}+\text{Breadth})$.

- Perimeter Calculation: Substituting the values, the perimeter is $2\times (50+10)=2\times 60=120$ cm.

- Options Analysis:

- Option 1: 60 cm is incorrect.

- Option 2: 110 cm is incorrect.

- Option 3: 120 cm is correct.
