The area of the garden is A = 6/7.
The length of the garden is l = 3/5.
The formula for the area of the rectangle is,
[tex]A=l\times w[/tex]Substitute the values in the formula to obtain the width of the garden.
[tex]\begin{gathered} \frac{6}{7}=\frac{3}{5}\times w \\ w=\frac{6}{7}\times\frac{5}{3} \\ =\frac{30}{21} \\ =\frac{10}{7} \end{gathered}[/tex]So answer is 10/7.
