Answer:
Option B.
Explanation:
It is given that the perimeter of the parallelogram ABCD is 30 cm.
Let measure of AB is x cm.
AD 3 cm more than twice AB.
AD = 2x + 3
Perimeter of ABCD is
[tex]Perimeter=2(AB+AD)[/tex]
[tex]30=2(x+2x+3)[/tex]
[tex]30=2(3x+3)[/tex]
[tex]30=6x+6[/tex]
[tex]30-6=6x[/tex]
[tex]24=6x[/tex]
Divide both sides by 6.
[tex]4=x[/tex]
The measure of AB is 4 cm.
Hence, the correct option is B.
