The area of a parallelogram is 100 square millimeters. The base is 4 milimeters. Find the height.

Area = base times height

100 = 4h
100/4 = h
25 = h

To find the height of a parallelogram, we need to use the formula:

Area = base x height

Given that the area is 100 square millimeters and the base is 4 millimeters, we can rearrange the formula to solve for the height.

Area = base x height
100 = 4 x height

To find the height, divide both sides of the equation by 4:

100 / 4 = height
25 = height

Therefore, the height of the parallelogram is 25 millimeters.
