Answer:
height of trapezium is 8 cm.
Step-by-step explanation:
Given:
Area of trapezium = 80 sq.cm.
Sum of the parallel sides = 20 cm.
As we know that,
Area of trapezium = (1/2) ×sum of parallel sides × height
∴ Height = (area of trapezium × 2 ) / sum of parallel sides
= ( 80 × 2) /20
= 160 /20 = 8 cm.

The area of trapezium is given as 80cm² with the sum of its parallel sides as 20cm.
Let h be the height of the trapezium, then,
A = 1/2 (sum ofthe parallel sides)×h
80 = 1/2(20) × h
h = 8cm
