Answer:
[tex]31\ ft[/tex]
Step-by-step explanation:
we know that
The scale is equal to
[tex]\frac{1}{10}\frac{cm}{ft}[/tex]
so
by proportion
Find how far apart should the actual trees be planted, if the trees are [tex]3.1\ cm[/tex] apart in the plan
[tex]\frac{1}{10}\frac{cm}{ft}=\frac{3.1}{x}\frac{cm}{ft}\\ \\x=10*3.1\\ \\x=31\ ft[/tex]
