To estimate the population total, you need to identify the value of N, which represents the total number of units in the population.
From the description of the garden plot, we have a grid of squares that covers an area of 15 meters by 18 meters. The squares are 3 meters by 3 meters.
To find N, we need to calculate the total number of squares in the grid:
- The total area is \(15 \text{ m} \times 18 \text{ m} = 270 \text{ m}^2\).
- Each square covers an area of \(3 \text{ m} \times 3 \text{ m} = 9 \text{ m}^2\).
Now, to find the number of squares (N), we divide the total area by the area of one square:
\[
N = \frac{270 \text{ m}^2}{9 \text{ m}^2} = 30.
\]
Therefore, the value of N is **30**.
