Find the area of a trapezium whose parallel sides are of lengths 10cm and 12cm and the distance between them is 4cm.

Explanation

To find the area of a trapezium with given parallel sides and the distance between them, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the lengths of the parallel sides and the distance between them.**
- Let the lengths of the parallel sides be \( a = 10 \) cm and \( b = 12 \) cm.
- The distance between the parallel sides (height) is \( h = 4 \) cm.
