If L = 55 and NOM = 28, what is N?
A. 27
B. 28
C.
42
D. 70

the answer on e2020 is

10

4/5

3/5

4/3

step-by-step explanation:

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: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
