RP=55cm^{2}
The equation is in standard form.
\frac{RP}{R}=\frac{55cm^{2}}{R}
Divide both sides by R.
P=\frac{55cm^{2}}{R}
Dividing by R undoes the multiplication by R.
PR=55cm^{2}
The equation is in standard form.
\frac{PR}{P}=\frac{55cm^{2}}{P}
Divide both sides by P.
R=\frac{55cm^{2}}{P}
Dividing by P undoes the multiplication by P.
