Question

the parallelogram shown below has an area of 120 units². find the missing base.

Explanation:

Step1: Recall area formula

The area formula for a parallelogram is $A = b\times h$, where $A$ is the area, $b$ is the base, and $h$ is the height.

Step2: Substitute known values

We know that $A = 120$ units² and $h=12$ units. Substituting into the formula gives $120=b\times12$.

Step3: Solve for base

To find $b$, we divide both sides of the equation by 12. So, $b=\frac{120}{12}=10$ units.

Answer:

10 units
