18. A police officer recorded the number of parking spaces in six different parking lots on a college campus. She used a stem-and-leaf plot ot organize the data.
Parking Spaces
Stem Leaf
32 044
337
3499
320 means 320 parking spaces.
Based on the data, how many parking spaces are in the six lots combined?

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
