What percent is represented by the shaded area?

30%

Step-by-step explanation:

There are 6 shaded squares out of 20 squares. That is the same as 30 out of 100. 30/100=30%

30%

Step-by-step explanation:

5*4 is 20.

So that your area.

6/20 converted to percentage: 30%

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

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
