In this question, the answer given in the big book is B which is 256. But technically the answer should be 96.
My Solving:
2(l+b)=40
2(l+8)=40
l=12
Area=(12*8)=96
There is limited information but is this a quantatative comparison question? Often times, when there are two values given, in this case “The area of R” and “256”, the answer choices are denoting their relationships.
a) A is greater
b) B is greater
c) A & B are equal
d) Not enough information to determine
If it is a question like this, then the answer would be “B” because 256 is greater than the area of R that you found to be 96. It seems like to me your work is correct but double check what the questions in the sections are actually asking.
