Solve =1386/2=693cm^2

$$= \frac { 1386 } { 2 } = 693 cm ^ { 2 }$$

Solve for c

$$c=\frac{1}{m^{2}}$$

$$m\neq 0$$

Steps for Solving Linear Equation

Divide 1386 by 2 to get 693.

$$693=693cm^{2}$$

Swap sides so that all variable terms are on the left hand side.

$$693cm^{2}=693$$

The equation is in standard form.

$$693m^{2}c=693$$

Divide both sides by 693m^{2}.

$$\frac{693m^{2}c}{693m^{2}}=\frac{693}{693m^{2}}$$

Dividing by 693m^{2} undoes the multiplication by 693m^{2}.

$$c=\frac{693}{693m^{2}}$$

Divide 693 by 693m^{2}.

$$c=\frac{1}{m^{2}}$$

Solve for m (complex solution)

$$m=-c^{-\frac{1}{2}}$$

$$m=c^{-\frac{1}{2}}\text{, }c\neq 0$$

Solve for m

$$m=\frac{1}{\sqrt{c}}$$

$$m=-\frac{1}{\sqrt{c}}\text{, }c>0$$
