Marcus walks at a rate of 2 ¾ miles in ¾ hours. Anna walks at a rate of 3 ½ miles in 1 ¼ hours. Which choice accurately shows the unit rate of the person that walks at a slower rate?

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
