ABCD is a parallelogram in whcih AB = 9.5 cm and its perimeter is 30 cm. find the length of each side of the parallelogram

 //gm has opposite sides equal

here AB=9.5 cm (given)

perimeter=30cm(given)

as its opposite sides are equal therefore CD=9.5cm ( because AB=9.5cm)

perimeter of //gm=2(AB+BC)

30=2(9.5+BC)

30-19=2BC

BC=11/2cm

BC=AD=5.5cm
