Answer:
5.33 yards
Explanation:
The area of a triangle can be calculated as:
[tex]\text{Area = }\frac{Base\times Height}{2}[/tex]We know the area and the height, so we can replace these values and get:
[tex]48=\frac{Base\times18}{2}[/tex]So, solving for the base, we get:
[tex]\begin{gathered} 48\times2=\frac{Base\times18}{2}\times2 \\ 96=Base\times18 \\ \frac{96}{18}=\frac{Base\times18}{18} \\ 5.33=\text{Base} \end{gathered}[/tex]Therefore, the length of the base of the garden is 5.33 yards
