Dear student,

Question:   A field is in the shape of a trapezium whose parallel sides are 25 m and 10 m. The non-parallel sides are 14 m and 13 m. Find the area of the field.

Let us draw BE || AD

Then ABED is a parallelogram BE = 13 m DE = 10 m EC = 15 m

For BEC,

Height of trapezium = 11.2 m

Area of field

= 196 m2
All the best.

The answer is 6√51 square centimetres.Same way as example provided above. In cases other than this, the area of a trapezium is calculated in another way
