The height of the trapezoid is "h". Area of a Trapezoid Worksheets. Thus, if its height will be doubled, it will lead to an increase in its surface area but this will not lead to its surface area getting doubled. I agree, we probably need some sort of auto-mod response. To learn how to calculate the area of a trapezoid if you only know the sides, scroll down! Consider a trapezoid of bases 'a' and 'b', and height 'h'. To find the area of a trapezoid, start by adding together the length of the bases, which are the 2 sides of the trapezoid that are parallel with each other.
