Its area is equal to its length, multiplied by its height
The height is the length of its altitude.

The area of a parallelogram (even with unequal adjacent sides) is still the base times the height. But the height is not the length of a side but the distance (at right angles to the base) between the base and the side parallel to it.
Its length and its perpendicular height Area = length*height
To find the height of a parallelogram, you divide the area by the base length. So in this case, the height of the parallelogram would be 115/12 = 9.58 to the nearest hundredth.
Base * Vertical distance between bases (height).
To find the area of a parallelogram, multiply the length of the base by the height. The height should be perpendicular to the base.
It is the length of its perpendicular height
height
height
it is the height!
Because the area of a parallelogram is length times perpendicular height and the area of a rectangle is also length times perpendicular height
