Usually we talk about rectangles having length (shown as 'l') and width (shown as 'w'), so the P = 2l + 2w.
You have the values to substitute for 'l' and 'w'

Collecting terms, we have

The area is found much the same way.
We know the area (A) of a rectangle = length times width = l * w.
Substituting what we know about l and w, we have:

Done.
