Three friends each pack a bag for a trip. Mandy's bag is 20% heavier than Kathleen's bag. Donna's bag is 25% lighter than Kathleen's bag. By what percent is Mandy's bag heavier than Donna's bag?

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

part a: 1.08

part b: 27.59

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet
