Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm.
The distance between parallel sides is 16 cm.
To find:
The area of a trapezium.
Solution:
The area of the trapezium is:
Where, are parallel sides and
is the vertical distance between the parallel sides.
Putting in the above formula, we get
Therefore, the area of the trapezium is 408 square cm.
