To calculate the area of a trapezium, you can use the formula:

Area = 1/2 * (a + b) * h

where a and b are the lengths of the parallel sides of the trapezium, and h is the height (perpendicular distance between the two parallel sides).

In this case:

a = 5.4 cm

b = 14.5 cm

h = 7.5 cm

Now, plug these values into the formula:

Area = 1/2 * (5.4 + 14.5) * 7.5

Area = 1/2 * 19.9 * 7.5

Area = 0.5 * 149.25

Area = 74.625 square cm

Therefore, the area of the trapezium is 74.625 square cm.
