Javier's fuel tank holds 12 gallons of gasoline when completely full. He had some gas in the tank and added
10.3 gallons of gasoline to fill it completely. How many
gallons of gasoline were in the tank before Javier
added some?

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
