Question

If ABCD is a parallelogram in which AB= 9.5 cm and it’s permiter is 30 cm . Find the length of each side of the parallelogram

Answer 1

Perimeter of

parallelogram= 2(l+b)

30 = 2(9.5+b)

30 = 46+2b

i.e. 2b = 30-46

2b = 4

b = 4/2

b = 2

Therefore, the length is 9.5 cm and breadth is 2 cm

Answer 2

Given AB=9.5cm
perimeter =30cm
perimeter of parallelogram=2(l+b)
=2(9.5+b)
=19+2b
30=19+2b
30-19=2b
11=2b
11/2=b
5.5=b
AB=9.5(GIVEN)
BC=5.5
CD=9.5(PARALLEL)
DA=5.5(PARALLEL)
