Answer:
Step-by-step explanation:
Part A
Area of the deck = Area of rectangle A + Area of rectangle B
              = (12 × 20) + (34 × 8)
              = 240 + 272
              = 512 square feet
Part B
∵ 200 square feet of the deck is covered by 1 can of stain
∴ 1 square feet of deck will be covered by the can of stain = [tex]\frac{1}{200}[/tex]
∴ 512 square feet will be covered by the stain = [tex]\frac{512}{200}[/tex]
                                       = 2.56
                                       ≈ 3
Therefore, 3 cans of stains will cover the entire deck.
