The lengths (in cm) of parallel sides of a trapezium are 2x and 3x -1, and the distance between
the parallel sides is x +1. If the area of the trapezium be 28 cm, find the smaller of the two
parallel sides.

Step-by-step explanation:
height =x+1
2 parallel sides are 2x and 3x-1
Area of trapezium = 1/2×(Sum of parallel sides) ×height
28=1/2×(2x+3x-1)× x+1
x=3
then, 1 parallel side= 2x=6
Another parallel side is x+1=8
