The formula for the area of a parallelogram is base times height. A parallelogram is a four-sided figure in which the opposite sides are parallel to one another and have the same length and the sum of all internal angles... More » Math Geometry Shapes

The area of a parallelogram can be calculated by multiplying the length of the base by the height to the top, perpendicular to the base. Either edge on either set of sides can be oriented to be the base. The formula for ... More »

The perimeter of a parallelogram, as for any polygon, is the sum of the lengths of its sides. The opposite sides of a parallelogram are parallel and have the same measurement. The formula for its perimeter is twice the s... More »

To find the height of a parallelogram, use the formula "base times height equals area." Divide both sides of the equation by the base to find the height. Height is equal to the area divided by base. More »

The formula for the area of any triangle equals 1/2 the base times the height. For a right triangle, this is easy to remember ,since a right triangle is half of a rectangle on one side of its diagonal, and the area of a ... More »

The area of any trapezoid with base side lengths "b1" and "b2" and height "h" is given by the formula A = h(b1 + b2)/2. The base sides are the trapezoid's two parallel sides. The trapezoid's height is the length of a per... More »
