The shape of the top surface of a table is a trapezium. Find its area if its parallel sides are 1 m and 1.2 m and perpendicular distance between them is 0.8 m.

Explanation

To find the area of the trapezium-shaped top surface of the table, we can follow these steps:

### Step 1: Identify the formula for the area of a trapezium.
The area \( A \) of a trapezium can be calculated using the formula:
\[ A = \frac{1}{2} \times (a + b) \times h \]
where:
