area=base x height

The formula is base x height. Remember, the height is the distance from one of the top vertices to the base AT A RIGHT ANGLE (not the measure of the slanted side). The best way to remember the formula is to think of a parallelogram as a modified rectangle. If you were to cut off one of the right triangles formed by drawing a line from a vertex to the base (at a right angle) and move it to the opposite end of the parallelogram you would create a rectangle whose length and width would correspond to the base and height of the parallelogram - got it? Therefore, the area of a parallelogram is base times height while the area of a rectangle is length times width - OK?
More interesting stuff - The formula for the area of a parallelogram is very similar to the formula for the area of a triangle - here's why:
if you draw one diagonal from opposite vertices, in a parallelogram, you form two identical triangles - always. The base of each triangle is the length of the base of the parallelogram and the height of each triangle is the distance from the base to the opposite vertex at a right angle to the base. The formula for the area of the parallelogram is BASE TIMES HEIGHT and that area is made up of two identical (congruent) triangles AND the formula for the area of a triangle is 1/2 BASE TIMES HEIGHT because it is exactly half the area of a parallelogram with the same base and height. How about that? Hope that helps!

Because a parallelogram is a deformed rectangle (a rectangle is in fact a special case of a parallelogram), the formulas for the area is the same. Length * height.

make a rectangle as big as possible inside the parallelogram and use length times width. then take one of the triangles left and use base times height divided by 2. repeat for the other triangle. to finish add up these answers to get total area of a parallelogram.

Area of a Parallelogram = Base * height. Answer.
Or a*b sin C, where a and b are adjacent sides and C is the angle between them.

Set L equal to the length of one side.
Construct a perpendicular to that side that intersects the opposite side.
Set H equal to the length of the perpendicular.
The area is equal to L*H
