WebA trapezoid is a four-sided closed shape or figure which cover some area and also has its perimeter. It is a 2D figure and not 3D figure. The sides which are parallel to each other are termed the bases of the trapezoid. The non-parallel sides are known as legs or lateral sides. The distance between the parallel sides is known as the altitude. WebThe area of the trapezoid is A = 1/2(a+b)h (1) = mh (2) = 1/4(b+a)/(b-a)eta.
