Two parallel side of a trapezium are `60 c m\ a n d\ 77 c m` and other sides are `25 c m\ a n d\ 26 c mdot` Find the area of the trapezium.

Explanation

To find the area of the trapezium with parallel sides of lengths 60 cm and 77 cm, and non-parallel sides of lengths 25 cm and 26 cm, we can follow these steps:

### Step 1: Identify the lengths of the sides
Let the lengths of the parallel sides be:
- \( a = 60 \, \text{cm} \) (one parallel side)
- \( b = 77 \, \text{cm} \) (other parallel side)

And the lengths of the non-parallel sides be:
