Question

The parallelogram shown below has an area of 212121 units^2

Answer 1

3 is the missing height. Khan sent me

Answer 2

Answer:

In this context, the missing height measures 7 units

Explanation:

The diagram for this problem is shown below. We know that a parallelogram is a quadrilateral where both pairs of opposite sides are parallel. The area (A) for any parallelogram is defined as:

$A=B\times H \\ \\ \\ Where: \\ \\ B:Base \ of \ the \ parallelogram \\ \\ H:height \ of \ the \ parallelogram$

From the figure, we know:

$B=3units$

And the statements tells us that the area is:

$A=21units^2$

So, substituting in our equation for the are:

$21=3H \\ \\ \\ Isolating \ H: \\ \\ H=\frac{21}{3} \\ \\ \boxed{H=7units}$

So in this context, the missing height measures 7 units
