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.

Answer»

Let the length of one parallel side of trapezium = x meter

Length of other parallel side of trapezium = (x + 8) m

Area of trapezium = 91 cm2

Area of trapezium = \(\frac{1}{2}\)(sum of sides) x distance between parallel sides

91 = \(\frac{1}{2}\)(x + x + 8) x 7

x + 4 = \(\frac{91}{7}\) 

x + 4 = 13

x = 13 - 4 = 9

Therefore length of one parallel side of trapezium = 9 cm

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