hello frnd!!!
here's ur answer...
given:-
height=18cm
let the parallel sides be 7x and 11x respectively.
b1=7x
b2=11x
area of the trapezium=306cm²
1/2×h(b1+b2)=306cm²
1/2×18(7x+11x)=306cm²
9×18x=306cm²
18x=306/9
18x=34
x=34/18
hence, b1=7x
=7×34/18
=238/18cm
b2=11x
=11×34/18
=374/18cm
hope this helps...
