Solution:

Consider the following expression:


p\text{ = 2(l+w)}

applying the distributive property, we get:

Equation 1:


p\text{ = 2l +2w}

solving for 2w, we get:


2w\text{ = p-2l}

solving for w, we get:


w\text{ = }(p-2l)/(2)

now, solving for 2l from equation 1, we get:


2l\text{ = p-2w}

solving for l, we get:


l\text{ = }(p-2w)/(2)

we can conclude that the correct answer is:


w\text{ = }(p-2l)/(2)

and


l\text{ = }(p-2w)/(2)
