Trapezoid: Area
How to find the area of a trapezoid: formula, 1 example, and its solution.
Formula
A = [1/2](b1 + b2)h
A: Area of a trapezoid
b1, b2: Bases
h: Height
Example
Solution
Solution (Detail)
The bases are 5 and 8.
h = 4
So A = [1/2](5 + 8)⋅4.
Cancel the denominator 2
and reduce 4 to, 4/2, 2.
5 + 8 = 13
13⋅2 = 26
So the area of the given trapezoid is 26.
