Explanation:

To find the area of a trapezium, use the formula: Area = (1/2) * (a + b) * h, where a and b are the lengths of the parallel sides, and h is the distance (height) between them.

- Given:

- Parallel side a = 25 cm

- Parallel side b = 19 cm

- Height (h) = 15 cm

- Calculation:

- Area = (1/2) * (25 + 19) * 15

- Area = (1/2) * 44 * 15

- Area = 22 * 15

- Area = 330 cm²

Now, let's review the options:

- Option 1: 330

- Option 2: 410

- Option 3: 345

- Option 4: 275

Based on the calculations:

- Option 1: 330 is correct.
