Answer:

Explanation:

To find the area of a trapezium with parallel sides AB and CD, we can use the formula:

Area = (AB + CD) * height / 2

In this problem, we know that:

AB = 30 cm

CD = 20 cm

DA = 9 cm

We can use these measurements to find the height of the trapezium:

height = DA = 9 cm

Now we can substitute these values into the area formula:

Area = (30 + 20) * 9 / 2

Area = 50 * 9 / 2

Area = 450 / 2

Area = 225 sq cm

So the area of the trapezium is 225 sq cm.

Note that this is only one of the ways to calculate the area of a trapezium and you could have also used the height(in this case 17cm) and the breadth to calculate the area of the trapezium as well.
