Find the area of a trapezium if the distance between its parallel sides is 26 cm and one of the parallel sides is 84 cm, the other parallel side is half of the perpendicular distance between the parallel sides.
1261 cm2
Area of trapezium = h (a+b)2sq. units
It is given that other parallel side is half of the perpendicular distance between the parallel sides i.e. half of 26 which is = 13 cm
⇒ 12 × (84 + 13) × 26
⇒ 12 × 97 × 26 = 1261 cm2
