Step-by-step explanation:
Let the length be 2x and 3x.
Height = 16cm
Area of Trapezium = 320 sq. cm
Area of Trapezium =
= 1/2 * h (a + b)
320 = 1/2*16 (2x+3x)
320 = 8*5x
320 = 40x
x = 8cm
LENGTH OF PARALLEL SIDES ARE 16 & 24 cm

Given :-
- The ratio of the length of parallel sides of a trapezium is 2:3 .
- The distance between them is 16 cm . If the area of the trapezium is 320 sq. cm.
To find :-
- Length of parallel sides =?
Solution :-
- Let the parallel sides be 2x and 3x.
☀️As it's given that the ratio of the length of parallel sides of a trapezium is 2:3 . Area of trapezium is 320 and the distance between parallel sides is 16 cm.
Formula used :-
Where :-
⎘ (a + b) is = Sum of parallel sides
⎘" h " is = Distance between parallel sides
⎘ First parallel side = 2x = 16cm
⎘ Second parallel side = 3x = 24cm
