Yes, certainly. The trapezoid area is one half sum of bases times height and the parallelogram area is base times height If the base of the parallelogram is equal to 1/2 the sum of he trapezoid bases, they have the same area

Square = parallelogram and a square trapezoid = trapezoid Parallelogram = Parallelogram

The formula for the area of a trapezoid is a combination of the formulas for the areas of a triangle and a rectangle. It can be seen as two congruent triangles placed together to form a parallelogram. So, the formula for the area of a parallelogram is a generalization of the formula for the area of a trapezoid.

trapezoid

of course base times height for a square or rectangle. but for a trapezoid a= h x "b1+b2"

A parallelogram is a degenerate trapezoid: as the longer of the parallel sides of a trapezoid shrinks to the length of the shorter parallel side, the trapezoid becomes a parallelogram. It is truer to say that the area of a trapezoid helps to find the area of a parallelogram: area_trapezoid = mean_average_of_parallel_sides x distance_between_them = 1/2 sum_parallel_side_lengths x distance_between_them When the parallel sides are of equal length this becomes: area = (1/2 x 2 x length_of_parallel_sides) x distance_between_them = length_of_parallel_sides x distance_between_them = area_parallelogram

A trapezoid is not a type of parallelogram. A parallelogram is a type of trapezoid.

is a trapezoid a parallelogram

They both use perpendicular height and are in square units. Area of a trapezoid = 0.5*(sum of parallel sides)*perpendicular height Area of a parallelogram = base*perpendicular height

No, a parallelogram is not always a trapezoid, but they are both four-sided quadrilaterals. A parallelogram has two pairs of parallel sides, and a trapezoid has only one pair of parallel sides.

A trapezoid is sometimes a parallelogram. If the trapezoid has two pairs of parallel sides, it will also be a parallelogram. However, if the trapezoid does not have two pairs of parallel sides, it will not be a parallelogram.

No, a parallelogram is not a trapezoid.
