The area of a trapezium is 1586 cm2 and the distance between the parallel sides is 26 cm. If one of the parallel sides is 38 cm, find the other.
Let the length of other parallel side of trapezium = 
Length of one parallel side of trapezium = 
Area of trapezium = 1586 cm2
Distance between parallel sides = 26 cm
Area of trapezium = 
1586 = 
Therefore the length of other parallel side of trapezium = 
15
