Be quick for my sakes find the difference using the number line. a number line ranging from two to three, with increments of one-fourth units. drag and drop a number into the box to match the subtraction problem with its difference.
2.25−(−0.25)
a: 2
b: 2.75
c: 2.5
c: 2.25

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

answer:

c. the third graph
