Notice that the line divides the trapezoid into two triangles: one triangle with base b_1 = B1, and another triangle with base b_2 = B2. Both triangles have height h = H.

The area of the trapezoid is equal to the sum of the areas of the two trapezoids.

The area of the trapezoid is equal to the sum of the areas of the two triangles.

A = \dfrac12 \cdot b_1 \cdot h + \dfrac12 \cdot b_2 \cdot h

Factor out \dfrac12 \cdot h to get the formula for the area of a trapezoid:

A = \dfrac12 \cdot h \cdot (b_1 + b_2) = \dfrac12 \cdot (b_1 + b_2) \cdot h
