side's are 17 and 23 cm
Aliter: 1/2(X+X+6)9=180
2x+6=40
X=17
we assumed that one side be X and other be X+6.
so, X=17&X+6=23cm.
Hope it's work Dear.

let first parrallel side be a
second be a+6
area of trapexium = 180
1/2x(a+a+6)x9 =180
1/2(2a+6)=180/9
a+3=20
a= 17
first side is 17cm
second side is 23cm
second be a+6
area of trapexium = 180
1/2x(a+a+6)x9 =180
1/2(2a+6)=180/9
a+3=20
a= 17
first side is 17cm
second side is 23cm
a+6=40
at least solve good Yaar
thankuu
from where 3 is come
2 is divided by 2a +6
I got it
thank
actually 1/2(2a+6) ....then i have divided 2a+6 by 2 which is equal to a+3
wlcm sweta:-)
