Answer 1

To estimate the population total of seeds in the garden plot, we need to calculate the total number of 3x3 meter squares within the entire plot.

The dimensions of the entire garden plot are 15 meters by 18 meters. To determine how many 3x3 squares fit into this plot, we first calculate the total area of the plot:

Area of the plot = Length × Width = 15 m × 18 m = 270 m².

Next, we calculate the area of each square:

Area of each square = 3 m × 3 m = 9 m².

Now, to find the total number of 3x3 squares (N) that can fit into the garden plot, we divide the total area of the plot by the area of one square:

N = Total area of garden plot / Area of one square = 270 m² / 9 m² = 30.

Therefore, the value of N is 30.
