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.
Simply get the value of the angle and distribute away.
