Answer 2

Answer:

the sum of parallel sides is 18 cm

Step-by-step explanation:

Given :

height of trapezium = 12 cm

area of trapezium = 108 cm

Area of trapezium

= 1/2 × h × ( sum of parallel sides )

but the area is given, we have to find the sum of

parallel sides

so, area = 1/2 × h × ( sum of parallel sides )

=> 108 = 1/2 × 12 × ( sum of parallel sides)

=> 18 = sum of parallel sides

hence, the sum of parallel sides is 18cm
