    Answer:

    As we know that rectangle has 4 sides.

    Let side be x.

    Therefore,

    side+side+side+side=perimeter

    (sum of all sides= perimeter)

    Now, we are going to put the value as they are given.

    x+x+x+x=56 cm

    (As we know that in rectangle there are total 4 sides where 2 sides of length and 2 sides of width)

    x+x+3x+3x=56 cm

    8x=56 cm

    Now, let’s divide both sides by 8.

    Hence, the value of x is 7.

    X=7 now let’s prove X is 8

    7+7+3(7)+3(7)=56 cm

    7+7+21+21=56

    14+42=56

    56=56 : 2 sides are 7 cm and 2 sides are 21 cm.

    Answer:

    Step-by-step explanation:

    Let the length of the rectangle be x  

    Breadth  = x/3

    Perimeter = 56 m  

    2(l+b) = 56 m  

    l+b = 28 m  

    x+x/3   = 28 m  

    4x = 80 m  

    x = 21 m  

    length = 21 m Breadth = 7 m
