In a physics experiment, scientists use the equation $R=\frac{bl}{d}$ to represent the resistance in a conductive wire. Rewrite this formula to represent the length of the wire in terms of $R,,$ and A where $p$ represents the resistivity and A represents the cross$-$sectional area of the wire. Use your equation to determine the Length of a wire with a resistance of $7,$ a resistivity of $2\mathrm{.}44{10}^{-8}*m,$ and a cross sectional area of $0\mathrm{.}02m^2.$

$R=\frac{PL}{A}$
