The formula for the area of a parallelogram is base times height. A parallelogram is a foursided figure in which the opposite sides are parallel to one another and have the same length and the sum of all internal angles... More »
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 »
Determine the area of a parallelogram by separating the shape into its component pieces and adding the individual areas together. A parallelogram can be broken into a quadrilateral and two triangles. More »
The area of a triangle is found by multiplying onehalf times its base times its height. According to Wolfram Mathworld, Beyer and Baker there are 110 formulas for the area of a triangle. 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 »
