Parallelogram Area Calculator
Find a parallelogram area from base and height.
Base times height
A parallelogram has the same area as a rectangle with the same base and height, because shearing a rectangle into a slant does not change its area. This calculator uses that fact.
A parallelogram with a base of 7 and a perpendicular height of 4 has an area of 28. Be sure to use the perpendicular height, not the slanted side.

Frequently Asked Questions
What is the formula?
The area is the base times the perpendicular height — the same as a rectangle with those dimensions.
Which height do I use?
The perpendicular distance between the base and its opposite side, not the slanted side length.
What units?
Any consistent unit; the area comes out in square units.
