They won't because you shouldn't smoke . I should know my dad's a smoker and he smokes 2 packs a day . when you do you inhale tar , carbondioxide , bezel . tar - the roads carbondioxide - chemicals bezel - very toxic stuff possibly found in cleaners it makes a fat substains that makes heart blockage, lung cancer ,brain cancer ,heart disease, gum disease ,oral cancer and half of the smokers in this world die from smokeing now my point is of telling you this is that you share this with people so that they DONT smoke . thank you,                                         Autumn

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
