The water level of a creek has risen 4 inches above its Flood stage. If it continues to rise steadily at 2 inches per
hour, how long will it take for the creek to be 12 inches
above its flood stage?

4 hours

Step-by-step explanation:

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
