Formula Parallelogram Area Height Side length
$$A ~=~ \class{blue}{a} \, \class{red}{h}$$ $$A ~=~ \class{blue}{a} \, \class{red}{h}$$ $$\class{red}{h} ~=~ \frac{A}{\class{blue}{a}}$$ $$\class{blue}{a} ~=~ \frac{A}{\class{red}{h}}$$
Area
$$ A $$ Unit $$ \mathrm{m}^2 $$ It is the area enclosed by the parallelogram.
Height
$$ \class{red}{h} $$ Unit $$ \mathrm{m} $$ Perpendicular height measured from one edge of the parallelogram to the other edge.
Side length
$$ \class{blue}{a} $$ Unit $$ \mathrm{m} $$ Length of the base side of the parallelogram. If \( a = b \), then it is a rhombus.
