- Set:

Answer:
1,2,3,4,6,8,12,24,
Step-by-step explanation:
P = 2w + 2h
factorise
P = 2 (w + h)
divide both sides by the coefficient of w + h
P ÷ 2 = 2 (w + h) ÷ 2
P/2 = w + h
make w the subject of the formula
w = h - p/2
This is how I solved it and the two answer choices. And the values that will make the equations true is in the second picture
