Question

find missing length when given area of a parallelogram
the parallelogram shown below has an area of 21 units².
find the missing height.
h = \boxed{} units

Explanation:

Step1: Recall area formula of parallelogram

The area \( A \) of a parallelogram is given by \( A = \text{base} \times \text{height} \), i.e., \( A = b \times h \).

Step2: Identify known values

Here, the base \( b = 7 \) units and the area \( A = 21 \) square units. We need to find the height \( h \).

Step3: Solve for height \( h \)

From \( A = b \times h \), we can rearrange to get \( h = \frac{A}{b} \). Substituting \( A = 21 \) and \( b = 7 \), we have \( h = \frac{21}{7} = 3 \).
