Answer: [tex]\dfrac{1}{10}[/tex] of an acre or 0.1 acre .
Step-by-step explanation:
Given : Andrea planted tomatoes and cucumbers on [tex]\dfrac{1}{5}[/tex]of an acre of land.
If each type of plant took up an equal area of Andrea's land, then the part of an acre land each type of plant covers is given by using division operation :-
[tex]=\dfrac{1}{5}\div2=\dfrac{1}{5}\times\dfrac{1}{2}[/tex] [Change2 by its reciprocal to convert division operation to multiplication ]
[tex]=\dfrac{1}{10}=0.1[/tex]
Hence, each type of plant covered [tex]\dfrac{1}{10}[/tex] of an acre.
