ABCD is a parallelogram in which AB = 9.5 cm and its perimeter is 30 cm. Length of each side of parallelogram ABCD is :
AB = 9.5 cm, DC = 9.5 cm, BC = 5.5 cm, DA = 5.5 cm
AB = 9.5 cm, BC = 9.5 cm, DC = 5.5 cm, DA = 5.5 cm
DC = 5.5 cm, BC = 5.5 cm, AB = 9.5 cm, AD = 9.5 cm
none of these

Answer
In a parallelogram, opposite sides are equal in length.
AB = CD
BC = DA
Perimeter = 30 cm
We know that,
Perimeter of Parallelogram = 2(Length + Breadth)
30 = 2(9.5 + BC)
15 = (9.5 + BC)
BC = 15 - 9.5
BC = 5.5 cm
BC = AD = 5.5 cm.
AB = CD = 9.5 cm
Hence, option 1 is the correct option.
