To find the total area of the dog park and community park in yards, we first need to convert the areas from square feet to square yards.
1 square yard is equal to \(3 \times 3 = 9\) square feet.
First, we will calculate the areas in square feet:
- Dog park: \(8.91 \times 10^3\) square feet
- Community park: \(2.6 \times 10^3\) square feet
Now, let's calculate the total area in square feet:
\[ 8.91 \times 10^3 + 2.6 \times 10^3 = 8.91 \times 10^3 + 2.6 \times 10^3 = 11.51 \times 10^3 \text{ square feet} \]
Next, we convert this total area into square yards:
\[ \text{Total area in square yards} = \frac{11.51 \times 10^3 \text{ square feet}}{9 \text{ square feet/square yard}} = \frac{11,510}{9} \approx 1,279.89 \text{ square yards} \]
Therefore, the total area of the dog park and community park is approximately 1,279.89 square yards.
