The length of two parallel sides of a trapezium are 15 cm and 20 cm If its area is 175 sq.cm, then its height is :

Solution:

Sum of the two parallel sides of the trapezium = 15 + 20 = 35 cm
Let its height = h cm
⇒ Area of trapezium =

1/2×

(sum of parallel sides) × height
⇒

⇒

h=175/35×2

⇒

h=5×2=10
