Area of Trapezoid Formula The area of a trapezoid is the average width times the altitude. B5 C5 2 D5 which calculates the area of a trapezoid given the length of side a in column B the length of side b in column C and the height h in column D. Property 2 Area of a Trapezoid A r e a h e i g h t sum bases 2 more Property 3 Trapezoids have a midsegment which connects the mipoints of the legs more Adjacent Angles of Trapezoid The angles on the same side of a leg are called adjacent angles such as A and D are supplementary.
It explains how to find the area given everything.
The trapezoids height is the length of a perpendicular line drawn between the two base sides. Area of trapezium sum of two parallel sides height. This geometry video tutorial explains how to find the area of a trapezoid using the formula A12b1b2h. On implementing it in the formula.
