# Area between a parabola and a chord

## Description

Parabola is a two-dimensional, mirror-symmetrical curve, which is approximately U-shaped. The area enclosed between a parabola and a chord is two-thirds of the area of a parallelogram which surrounds it. One side of the parallelogram is the chord, and the opposite side is a tangent to the parabola.The slope of the other parallel sides is irrelevant to the area. If the chord has length b, and is perpendicular to the parabola’s axis of symmetry, and if the perpendicular distance from the parabola’s vertex to the chord is h, the parallelogram is a rectangle, with sides of b and h.
