**16+ Cross Sectional Area Of Trapezium Background**. This video talks through three examples of finding the area of a trapezium. Learn area of trapezium topic of maths in details explained by subject experts on vedantu.com.

My solution so far goal: If we know any three we can always find the fourth. (jump to area of a trapezoid or perimeter of a trapezoid).

### Solving linear equations using cross multiplication method.

If we know any three we can always find the fourth. △bpc is right angled at ∠bpc. To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then. The unit of cross sectional area will depend on the length unit used for radius measurement.
