Step-by-step explanation:
Look at the picture.
We connect two congruent trapezoids as in the picture.
We created a parallelogram with a base length of b₁ + b₂ and a height h equal to the height of the trapezoid.
The formula of an area of a parallelogram:
The area of the trapezoid is half of the parallelogram area.
Therefore we have the formula of an area of trapezoid:
Therefore we need to be added the bases of a trapezoid.
