Area of a trapezoid. The area of a trapezoid is the space contained within its perimeter. The grey space is the area of the trapezoid in the diagram below. Area formula of a trapezoid. The area, A, of a trapezoid is: where h is the height and b 1 and b 2 are the base lengths. Derivation
The formula for the area of a trapezoid is A = ½ (b 1 +b 2)h, where b 1 and b 2 are the lengths of the bases and h is the height. [1] If you only know the side lengths of a regular trapezoid, you can break the trapezoid into simple shapes to find the height and finish your calculation.
To find the area of a trapezoid (A), follow these steps: Find the length of each base (a and b). Find the trapezoid's height (h). Substitute these values into the trapezoid area formula: A = (a + b) × h / 2.
What is the Formula for Area of Trapezoid? The formula that is used to find the area of a trapezoid is expressed as, Area of trapezoid = ½ (a + b) h; where a' and 'b' are the bases (parallel sides) and 'h' is the height of the trapezoid.
Use the formula for the area of a trapezoid. \text {Area of trapezoid}=\cfrac{1}{2} \, \times h \times(\text {base } 1+\text {base } 2) The parallel sides are the bases, where one base is the shorter base and the other is the longer base. Area of the rectangle:
The area of a trapezoid is basically the average width times the altitude, or as a formula: Area. = h. ·. b. 1. +. b. 2. where. b1, b2 are the lengths of each base. h is the altitude (height) Recall that the bases are the two parallel sides of the trapezoid.
Trapezoid area formula. In general, if b 1 and b 2 are the bases of a trapezoid and h the height of the trapezoid, then we can use the formula below. The area of a trapezoid is half the sum of the lengths of the bases times the altitude or the height of the trapezoid.
