Answer 2

5 cm

Explanation:

I believe there is a type, w seems to equal to 1 /2. If it is, follow the steps below.

We are asked to find the value of P where l = 2 and w = 1/2 in P = 2(l + w).

If we substitute the given values into the equation, we will have the following:

P = 2 ( 2 + 1/2)

When we make the calculation, we get:

P = 2(5/2) = 5 cm
