total surface area Stot = 688 mm2
lateral surface area Slat = 324 mm2
top surface area Stop = 182 mm2
bottom surface area Sbot = 182 mm2
Answer:
C
Step-by-step explanation:
The y intercept is 2 and if you do the rise/run you'll find that the slope has to be 1/2
this means our equation has to be
1/2x+2
To solve this you would make a triangle, Assuming you had a piece of paper.
It would look like the picture included (where ever that is) sorry for the horrible drawing with mouse.
You can then you Pythagorean Theorem to solve this

width will be (a)
put in your variables


Subtract 5184 over and get

square root both sides and get
a=54
the field is 54 meters wide
Food = 1/4
gasoline = 3/5
Total = 1/4 + 3/5 = 17/20
17/20 = 272
1/20 = 272 ÷ 17 = 16
20/20 = 16 x 20 = $320
