Answer:

Step-by-step explanation:

perimeter of parallelogram =sum of all sides

30=AB+BC+CD+AD

30=10+BC+10+BC(Opposite sides of parallelogram are congruent. Therefore, AB=CD=10,BC=AD.)

*we can write BC instead of AD as they both are equal*

30=20+2BC

30-20=2BC

10=2BC

10/2=BC

5=BC

therefore length of AB=10cm,BC=5cm,CD=10cm,AD=5cm.
