Only by the definition of a perimeter.
It is not in all but a trivial sense - that they are both to do with finding the perimeter!
Area = length x width you may try the online calculator linked below that is related to this area and perimeter calculation of common shapes like rectangle, circle, triangle, parallelogram, rhombus and trapezoid.
If the heights and bases are the same, then the triangle is half the area of the parallelogram.
They are both convex polygons.

The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
If the heights and bases are the same, then the triangle is half the area of the parallelogram.

sideways
the area of a triangle is half that of a rectangle made using two of those triangles.
It's half the area of a rectangle
Area of a triangle = 0.5*base*perpendicular height Area of a parallelogram = base*perpendicular height
The area of a parallelogram is the length times the vertical height. In a rectangle, the vertical height is the same as the width so the area is length times width.
