Answer: choice B) 2 by 6</h3>
===============================================
How I got that answer:
Opposite sides of the rectangle are the same length, so
y = 2x-4 (horizontal sides)
3y = x+3 (vertical sides)
-----------
Start with the second equation. Replace the 'y' with (2x-4) which is from the first equation. This replacement will allow us to solve for y
3y = x+3
3(2x-4) = x+3 .. replaced y with (2x-4)
6x-12 = x+3 ... distribute
6x-12+12 = x+3+12 ..... add 12 to both sides
6x = x+15
6x-x = x+15-x ..... subtract x from both sides
5x = 15
5x/5 = 15/5 ........ divide both sides by 5
x = 3
----------
Now we know the value of x, which means we can find the value of y
y = 2x-4
y = 2*3-4 .... replace x with 3
y = 6-4
y = 2
So the horizontal side is 2 units long
The vertical side is therefore 3y = 3*2 = 6
or we can say x+3 = 3+3 = 6 getting the same answer

The mark up percentage of each order is 400%
<h3>How to determine the percentage mark up?</h3>
The given parameters are:
Cost price = $4
Selling price = $20
The mark up percentage is calculated as:
Mark up percentage = (Selling price - Cost price)/Cost price * 100%
Substitute the known values in the above equation
Mark up percentage = ($20 - $4)/$4 * 100%
Evaluate the difference
Mark up percentage = $16/$4 * 100%
Evaluate the quotient
Mark up percentage = 4 * 100%
This gives
Mark up percentage = 400%
Hence, the mark up percentage of each order is 400%
