    Let the length be 4x and breadth be 3x. Given, Perimeter = 154 cm 2 ( Length + Breadth) = Perimeter of Rectangle 2 ( 4x + 3x ) = 154 2 ( 7x ) = 154 2 × 7x = 154 14x = 154 x = 154÷14 x = 11 Length = 4x = 4×11 cm = 44 cm Breadth = 3x = 3×11 cm = 33 cm

    Let, l=4x cm and b= 3x cm The perimeter of rectangle= 154cm Perimeter of rectangle=2(l+b) 154 is equals to 2(4x + 3x) 154= 14x X= 154 is divided by 14 X= 11 L= 4x= 4×11= 44 B= 3x= 3×11= 33 So, the write ans. Is 44cm and 33cm

    Let, the length is 4x cm and the breadth is 3x cm

    The perimeter of rectangle is 154 cm

     

    Perimeter of rectangle = 2 ( l + b )

    154 = 2 ( 4x + 3x )

    154 = 2 ( 7x )

    154 = 14x

    x = 11

    Length = 4x = 4×11 = 44cm

    Breadth = 3x = 3×11 =33cm
