#### Solution

Given:
Sum of the parallel sides of a trapezium = 60 cm
${\text{ Area of the trapezium }= 600 cm}^2$
$\text{ Area of trapezium }=\frac{1}{2}\times(\text{ Sum of the parallel sides })\times(\text{ Height })$
On putting the values:
$600 = \frac{1}{2} \times 60 \times (\text{ Height })$
$600 = 30 \times (\text{ Height })$
$\text{ Height }=\frac{600}{30}= 20 cm$
