The area of the parallelogram is 273 square units. What is the height of the parallelogram? ____units

Alex17521 [72]

Answer:

h = 13 units²

Step-by-step explanation:

The way to find the area of a parallelogram is to multiply the length of one side (21) and multiply it by the height:

A = l*h

We know the area and the length:

273 = 21*h

Now we solve for height.

273/21 = (21*h)/21

273/21 = h

273/21 = 13

h = 13 units²

If you're familiar with the quadratic equation
$\frac{ -b \pm \sqrt{b^2-4ac}}{2a}$

well, $\frac{ -b}{2a}$ is the x component of the vertex, in your case, the vertex is the highest point

figure out what t is at the highest point, and then substitute that back into the equation in order to determine height

x=t in this problem
