Perimeter of parallelogram,
2(b+h) = 20cm
Ratio of the adjacent sides = 3:2
Let the sides be x say
Then, the ratio becomes to 3x:2x
As per problem,
- 2(3x+2x) = 20cm
- 2(5x) = 20cm
- 10x = 20cm
- x = 20cm/10
- x = 2 cm
therefore, the value of x is 2cm
The adjacent sides,
- 3x = 3×2cm = 6cm
- 2x = 2×2cm = 4cm
Therefore, the adjacent sides are 6cm & 4cm
