Answer:
Step-by-step explanation:
Area of trapezium = 105 cm^2
Distance between the parallel sides = 7 cm
Let a parallel side be x
Other parallel side = x+6
Area = (1/2)*(sum of parallel sides) *(distance between them)
(105 *2)/7 = 2x+6
30 -6 = 2x
x=12
Another parallel side = 18 cm
First parallel side = 12 cm
