The diagrams shows the dimensions of an outdoor deck. The deck is going to be coated with a water sealer. A one-gallon container of water sealer costs $34 and covers approximately 200 square feet. What is the cost to buy enough containers of water sealer for the deck? A. $34
B. $68
C. $83
D. $102

So to find the answer we need to know the area of the deck by splitting each individual part into smaller shapes.

So for the rectangle up top we have: 50ft
Then for the triangle: 12.5ft
Then another rectangle above the triangle which is: 50 ft
Then the biggest rectangle is: 375ft

We would add this all together.

50+50+375+12.5=487.5

So one gallon costs $34 and covers 200 ft

So 487.5/200=2.437->multiply it by 34 and get 82.8 or $83

Your answer is $83
