11.3 The Area of a Trapeziod b2b2 b1b1 h

T102: The area of a trapezoid equals one-half the product of the height and the sum of the bases. A trap = h(b 1 + b 2 ) Where b 1 is the length of one base, b 2 is the length of the other base, and h is the height.

Median of a Trapezoid The line segment joining the midpoints of the non-parallel sides of a trapezoid is called the median of the trapezoid. CL Z U X E Y

T103: The measure of the median of a trapezoid equals the average of the measures of the bases. M = (b 1 + b 2 ) Where b 1 is the length of one base and b 2 is the length of the other base.

T104: The area of a trapezoid is the product of the median and the height. A trap = Mh Where M is the length of the median and h is the height.
