The area of a parallelogram can be calculated by multiplying its height by its base, following the formula:

If we know the area and the base of the parallelogram, we can determine the height of the parallelogram by dividing the area by the base:

The base has a measure of 4cm and the area is 12cm², using the expression above you can determine the height as follows:
![\begin{gathered} h=(12)/(4) \\ h=3\operatorname{cm} \end{gathered}]()
The height of the parallelogram is 3cm
