(a) Sea level is 0 , therefore the elevation of city (A) is -96 , and the elevation of city (C) is -24 For this part we do not need the elevation of city (A). The elevation of city (D) is 1/4 of city (C). The key word is OF! Of means to multiply. Therefore we have the expression 24 · 1/4 = -6. As for explaining why it's negative we go back to how a negative times a positive is a negative.
Answer:

Step-by-step explanation:
Given
piece of plywood measuring 2 feet 8 inches long by 2 feet 4 inches wide.
What is the area of a piece of plywood .
To proof
Here plywood shape in the form of rectangle.
Formula
Area of rectangle = Length×Breadth
As given in the question
Length =2 feet 8 inches
Breadth = 2 feet 4 inches
First convert feet into inches
1 feet = 12 inches
2 feet 8 inches = 2×12 + 8
= 32 inches
Also
2 feet 4 inches = 2×12 +4
= 28 inches
put is in the above formula
Area of plywood = 32 ×28
= 896 inches²
Therefore option (b) is correct
Hence proved
