l =x
b=2x
perimeter- 2×x+2x
24 - 2×3x
24 -6x
24÷6 - x
4 -x
longest side =2x =2×4=8cm

i did not understand how did u get 4-x=2x=2*4=8
i used -in place of=
did you understand
can u wait

Answer:
Given ABCD is a parallelogram, with two adjacent sides AB and BC being in the ratio 2:1 and its perimeter being 24 cm.
Let the length of side AB and BC be 2x and x respectively.
Since the opposite sides of a parallelogram are equal,
AB= CD = 2x cm and BC = AD = x cm
Now, perimeter = 24 cm
⇒
AB + BC + CD + AD = 24 cm
⇒
2x + x + 2x + x = 24 cm
⇒
6x = 24 cm
⇒
x = 4 cm
∴
The length of the adjacent sides AB and BC are 8 cm and 4cm respectively.
