What is the perimeter of a parallelogram with sides 11/12 and 4/9?

##49/18=2 13/18##
The opposite sides of a parallelogram are ##color(blue)parallel and equal in length##
Thus perimeter ##=(2xx11/12)+(2xx4/9)##
##=cancel(2)^1xx11/cancel(12)^6+8/9=11/6+8/9##
To add fractions we require a common denominator in this case 18.
##=(11xx3)/(6xx3)+(8xx2)/(9xx2)=33/18+16/18##
simplifying.
##33/18+16/18=49/18=2 13/18##
