area of trapezium = 1/2(side 1+side 2)*heightlet let the one side be =x cm
another is 54 cm long =x+54cm
height is distance =13 cm
acc to ques
1/2(x+x+54)*13=780
1/2(2x+54)*13=780
2x+54=780*2/13
2x+54=120
2x=120-54
x=66/2=33
answer is side one =33cm
other is x+54=33+54=87
another is 54 cm long =x+54cm
height is distance =13 cm
