A homeowner wants to make a new deck for his backyard. Redwood costs $5 per square foot. The units on the graph are in feet. How much will it cost to create the deck shown?
To find the cost to create the deck shown, we need to determine the area of the deck and then multiply it by the cost per square foot.
To find the area of the deck, we need to calculate the length and width of the rectangle shape shown on the graph.
Looking at the graph, we can count the number of squares within the rectangle shape to determine its length and width.
Counting the squares, we can see that the length of the rectangle is 8 squares and the width is 5 squares.
To calculate the area, we multiply the length by the width:
Area = Length × Width
Area = 8 feet × 5 feet = 40 square feet
Now that we have the area of the deck, we can calculate the cost by multiplying it by the cost per square foot:
Cost = Area × Cost per square foot
Cost = 40 square feet × $5/square foot = $200
Therefore, it will cost $200 to create the deck shown.
