Let one parallel side be x
Therefore other parallel side be x+8
Area of Trapezium is 198 cm2
Height = 9cm
Area of Trapezium = 1/2 (sum of its parallel side) × height
198 = 1/2 × (x+8 +x) ×9
198 = 1/2 ×(2x +8 ) ×9
198 /9 = x + 4
22 = x+ 4
x = 20
One parallel side is 20 cm
And other parallel side is 20+8 =28cm
