Answer:
The width of bookcase D is 61 cm
The width of bookcase E is 61 cm
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Sum the widths of the three bookcases A, B and C
step 2
Subtract the sum of the three bookcases A,B and C from the total length of the wall
step 3
Divide that answer in step 2 by 2, and that will let you know the widths of D and E, because they may have equal widths
therefore
The width of bookcase D is 61 cm
The width of bookcase E is 61 cm
you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B
Ok, so I'm pretty sure you get it by just dividing 168 by 182 to get 0.923 etc. Then if you multiply it by 100 then you get your grade. Which is about a <em>92.3%</em>. Hope this helps.
