Answer 2

Answer:

=> The perimeter is $20$ cm.

Step-by-step explanation:

Given that:-

The length of the rectangle = $7.5$ cm

The breadth of rectangle = $2.5$ cm

To find:- Perimeter = ?

We know that,

For the perimeter we have to use the formula:

=> Perimeter = $2$ ( $l+b$ )

Now, plug all the given values in the formula:

=> Perimeter = $2(7.5+2.5)$

Add all the terms in the brackets,

=> Perimeter = $2\times 10$

                     = $20$ cm

Hence, the required perimeter is $20$cm.
