Find the height of a parallelogram with base 6.75m and an area of 218.72 square meters

oksian1 [2.3K]

Answer:

about 32.4 meters

Step-by-step explanation:

The area of a parallelogram is the equation A=Base times Height.

Put in the known values 6.75m and 218.72meters squared into the equation.

It becomes the total area 218.72 = 6.75(h)

To get h or height by itself, you have to divide both sides by 6.75. You will get the answer 32.402, or you can round it to 32.4 meters.
