John has 2,456 pennies on his coin collection he has the same number of pennies in 3 boxes

There will be 818.67 pennies in two of the boxes, but in the third there will be two pennies left over.

818.67+818.67=1,637.34 + 818.66=  2,454

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
