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.
