Answer: OPTION A.
Step-by-step explanation:
The Standard form of the Equation of a line is the following:

Where "A", "B" and "C" are integers (
)
Given the equation of the line in Slope-Intercept form:

You can follow these steps is order to rewrite it in Standard form:
1. Subtract 5 from both sides of the equation:

2. Subtract "y" from both sides of the equation:

Therefore, the equation of the given line in Standard form is:

I think it’s 11. Sorry if it’s wrong
Triangle formula: 1/2base(height)
So 1/2(6) * 9
3*9 = 27ft^2
Parallelogram formula: length(width) or base(height)
So 18(13)= 234m^2
Triangle formula above so 1/2(20)*9
So 10*9 = 90in^2
OptionC is the answer..!!
Hope this helps you!!!
