Question

the parallelogram shown below has an area of 21 units². find the missing height. h = units

Explanation:

Step1: Recall area formula

The area formula for a parallelogram is $A = base\times height$, where $A$ is the area, and the base and height are perpendicular to each other. Here, the base $b = 7$ and $A=21$.

Step2: Solve for height

We have $A = b\times h$. Rearranging for $h$, we get $h=\frac{A}{b}$. Substituting $A = 21$ and $b = 7$ into the formula, we have $h=\frac{21}{7}$.
