two parallel sides of a trapezium are 4 cm and 5 cm respectively . the perpendicular distance between the parallel sides is 6 cm . find the area of the trapezium .
area of trapezium when height and two parallel sides are given = 1 / 2 × h × ( a + b ) = 1 / 2 x 6 x ( 4 + 5 ) = 27 cm 2 answer d
multiply(divide(add(4, 5), const_2), 6)
