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.

Here, ABCD is a trapezium and AB || DC.

Here, ABCD is a trapezium and CE || DA and

Now, AB = 25 m, BC = 14 m, CD = 10 m, DA = 13 m, AE = 10 m and CE = 13m

Now, for

Now, Area of triangle

=

(Since, Heron's formula [area =

=

=

=

=

Also, Area of triangle

=

=

Now, area of the trapezium ABCD

=

=

=

=

= 35 × 5.65

Therefore, the area of the field is 196
