127

Step-by-step explanation:

I think i am not sure sorry if I am wrong and yes if i am Right

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
