    Acoding to question Let the smaller side be x , Therefore the perimeter of the parallelogram is 36cm and longer side is 4cm. 4+x Perimeter=2(l+b) =2 (x +x+4)=2+2x+8=4x+8 p=36=36=4x+8=36-8=28%4=7

    Let the l of smaller side be x Therefore, l of long side be 4 +x Perimetre=2(l+b) =2(x+x+4)=2×2x+8 =4x+ 8 P=36 =>36=4x+8 =>36-8=4x =>28/4=x =>x=7 L=7

    Let the length of the smaller side (length) be x cm.

    Then, length of longer side (breadth) = x + 4 cm

    Then, it's perimeter,

    = 2 × length + 2 × breadth

    = 2 × x + 2 × (x + 4)

    = 2x + 2x + 8

    = 4x + 8

    But, given Perimeter = 36 cm.

    => 4x + 8 = 36

    => 4x = 36 - 8

    => 4x = 28

    => x = 28/4

    => x = 7 cm

    •°• Length = x = 7 cm

    •°• Breadth = x + 4 = 7 + 4 = 11 cm.

    ♥ So, the length of its side are 7 cm and 11 cm.
