Answer 2

30 cm

Explanation:

To find the perimeter you will have to use the formula L2 + W2 = A

1. Multiply the length (let's say 10 cm) by 2

a. 20

2. Do the same for width (5 cm)

a. 10

3. Add together

a. 20 + 10 = 30 cm

(There is another way to do it but this is easier)

Hope this helps :)
