#"Measure of" # #bar(BC)=32# units

Explanation:

Here #ABCD# is a parallelogram .

#BC=3x+5 and AD=5x-13#

We know that opposite sides of parallelogram are congruent.

#"So ,the measure of "##bar(BC)=# #"the measure of "##bar(AD)#

#=>3x+5=5x-13#

#=>13+5=5x-3x#

#=>18=2x#

#=>x=9#

Hence ,

#BC=3x+5=3(9)+5=32# units
