Area of a trapezium is 1/2x sum of parallel side x distance b/w them
To find the distance between parallel sides:
Draw perpendicular from A and B to the opposite parallel side.
Therefore the third side is divided in the ratio 5:10:5.
Therefore two right triangles are obtained. By Pythagoras theorem
13x13- 5x5 the whole square = 12
Therefore area if trapezium = 1/2 x 25+10 x 12
= 35×6
=210 sq. Units
