Let the one Parallel side be a cm
Second Parallel side =(a+8) cm
Area of trapezium = 198
=> (a+b) *h /2 = 198
=> (a+a+8) 9 /2 = 198
=> (2a +8)/2= 22
=> a+ 4 =22
=> a =18 cm
b = 26 cm
Second Parallel side =(a+8) cm
Area of trapezium = 198
=> (a+b) *h /2 = 198
=> (a+a+8) 9 /2 = 198
=> (2a +8)/2= 22
=> a+ 4 =22
=> a =18 cm
b = 26 cm
