Trapezoid Area
A=(b1+b2)h/2 and height MUST be perpendicular to the base
To find the area of a trapezoid, you need to use the following formula:
A = (b1 + b2) /2 * h
where A represents the area, b1 and b2 are the lengths of the parallel bases of the trapezoid, and h is the height of the trapezoid.
Here’s an example: Let’s say you have a trapezoid with a base of 4 cm and a parallel base of 8 cm. The height of the trapezoid is 5 cm.
To find the area of this trapezoid, you would use the formula:
A = (4 + 8) / 2 * 5
A = 12 / 2 * 5
A = 6 * 5
A = 30 cm^2
Therefore, the area of this trapezoid is 30 cm^2.
