find the height and of a parallelogram if its base is 35 centimeters and its area is 700 square centimeters
OLEGan [10]
Hello!

We know what the base and area of the parallelogram are, but the height is still unknown. We also know that the formula for the area is: 

A = bh

Meaning we multiply the base by the height to find the area. The opposite of multiplication is division, so we must divide the area by the base to find the height. (We work in the opposite way).

B = a / h 

B = 700 cm² / 35 cm

B = 20 

We can double check by multiplying 20 by 35, and the product should result in 700. 

20 * 35 = 700

Therefore, the height of the parallelogram is 20 centimetres.
