Answer:

i think its c?

Explanation:

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.
