## How do you find the centroid of a trapezoid?

Centroid of a Trapezoid System

1. A trapezoid is a quadrilateral with two sides parallel. The centroid of a trapezoid lies between the two bases. For any trapezoid with parallel sides a and b, use beneath given method.
2. Find beneath method for the centroid of trapezoid situated a distance of x,
3. LARGE x = frac{b+2a}{3(a+b)}h.

## How do you find the lacking aspect of a trapezoid?

Since this downside offers the size for each of the bases in addition to the complete perimeter, the lacking sides will be discovered utilizing the following method: Perimeter= Base one Base two (leg), the place the size of “leg” is one of the two equal nonparallel sides.
