Answer:
A. 0.15 flowers/ft²
Explanation:
The population density of flowers is the number of flowers per square foot.
To find the population density, we need to know the area of the garden and the number of flowers.
The area of the garden is 12 feet*18 feet =216 square feet.
The number of flowers is 32.
The population density is 32flowers/216square feet = 0.15 flowers/ft².
Therefore, the answer is (A).
