The length is 3/8 inches and width is 3/8 inches.
It is also given that the area of a capacitor plate is obtained by multiplying the length by the width.
To find the area of a capacitor plate by multiplying the length by the width,
[tex]A=l\times w[/tex]Substitute the values,
[tex]\begin{gathered} A=\frac{3}{8}\times\frac{3}{8} \\ A=\frac{9}{64}sq.in \end{gathered}[/tex]The area of capacitor plate is
[tex]\frac{9}{64}in^2[/tex]
