let one side of trapezium is X
area of trapezium=1/2(sum of parellel side).height
180=1/2 (X+X+6).9
2X+6=40
X=17
hence one side is 17cm and other is 23cm
area of trapezium=1/2(sum of parellel side).height
180=1/2 (X+X+6).9
2X+6=40
X=17
hence one side is 17cm and other is 23cm

Area of trap.=1/2(b1+b2)h
Then mention area of trap. after mention X + 6X in bracket at one side then all values take to left side then solve. Whatever will be the answer solve for that like X+6X= answer on left side whatever u will get after solving then take X on right side and answer-6 on left side. Value of X will come and then multiply by 6 to get 6X.
