The area of a trapqzium is 384 cm2. Its parallel sides are in the ratio 3 : 5 and the perpendicular distance between them is 12 cm. Find the length of each one of the parallel sides.

Let the length of one parallel side of trapezium =


Length of other parallel side of trapezium =


Area of trapezium = 384 cm2


Distance between parallel sides = 12 cm


Area of trapezium =


384 =





Therefore length of one parallel side of trapezium = 3x = 3× 8 = 24 cm


Length of other parallel side of trapezium = 5x = 5× 8 = 40 cm
