Use the definition of absolute value.
The absolute value is always non-negative. So if 
is already non-negative, 
is unchanged. But if is negative, then 
because multiplying by -1 makes it positive.
Now, if 
, then by the definition of absolute value,
The total area would be the combined area of all three
Let’s knock out the first 2
4.5 * 13 = 58.5 * 2 = 117
Now the last
4.5 * 9 = 40.5
117 + 40.5 = 157.5 ft^2
The answer to the question is a. 60°
