Which of the following represents the expression n divided by 3 in words? A The quotient of a number n and 3.
B The difference between n and 3.
C The sum of n and 3.
D The product of n and 3.

The answer is A.

Step-by-step explanation:

quotient is the answer of a division problem, so the answer is a

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
