A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply. read more

Understand why the formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle. read more
