caretGeometry Definitions

What is area?

Area is the size of a surface.

What is a trapezoid?

A trapezoid (as defined in the US) is a two-dimensional shape that is a quadrilateral with one pair of sides that are parallel.

caretGeometry Formula

The formula to calculate the area of a trapezoid is:

A = ½(a+b) x h

where...

  • A = area of trapezoid
  • a = top of parallel sides of trapezoid
  • b = base of parallel sides of trapezoid
  • h = height of trapezoid
