Answer:
681 Trees
Step-by-step explanation:
Given
[tex]Land\ Area = 5\ acre[/tex]
[tex]Unit\ Tree = 16ft\ by\ 20ft[/tex]
Required
Determine the number of trees
First, we need to calculate the area occupied by each tree
[tex]Area = 16ft\ * 20\ft[/tex]
[tex]Area = 320ft^2[/tex]
Next, is to determine the number of trees using the following formula
[tex]Number = \frac{Land\ Area}{Unit\ Tree\ Area}[/tex]
[tex]Number = \frac{5 Acre}{320ft^2}[/tex]
Convert Acre to ft²
[tex]Number = \frac{5 * 43560 ft^2}{320ft^2}[/tex]
[tex]Number = \frac{217800 ft^2}{320ft^2}[/tex]
[tex]Number = 680.625[/tex]
[tex]Number = 681\ trees\ (Approximated)[/tex]
