The area of a trapezium is 91 cm2 and its height is 7 cm. If one of the parallel sides is longer than the other by 8 cm, find the two parallel sides.

Let the length of one parallel side of trapezium =


Length of other parallel side of trapezium =


Area of trapezium = 91 cm2


Area of trapezium =


91 =





Therefore length of one parallel side of trapezium = 9 cm


Length of other parallel side of trapezium = 9+8 = 17 cm
