Explan why the formula for the area of a trapezoid contains the expression b +b

Answer:
Step-by-step explanation:
Actually, it doesn't.
A trapezoid has 2 sides which are parallel but of different lengths. It also has a width.
To find the area of a trapezoid, you find the average of the parallel side lengths and then mult. this result by the width:
a + b ← where a and b are the unequal side lengths
--------- * width
