Question

A trapezium has an area of 150cm^2.

The lengths of its parallel sides are 4.8 cm and 5.2 cm.
What is the perpendicular height of the trapezium?

Answer 1

Explanation:

Area of Trapezium=1/2 (a+b)h =>

1/2(4.8+5.2)h=15 => h=15/5 =3 cm Ans

Answer 2

Area of trapezium = ½ x (Sum of parallel sides) x (perpendicular distance between the parallel sides).

A = 1/2 h(a+b)

150 = 1/2 h(4.8+5.2)

150 = 5h

h = 30 cm

Answer - perpendicular height of the trapezium is 30 Cm
