The length and the breadth of a rectangle are rounded off to the nearest centimetre.The perimeter of the rectangle is 26cm.What are the possible values of its length and breadth.

  • math -

    L = Length

    B = Breadth

    P = Perimeter


    P = 2 L + 2 B = 2 ( L + B )

    26 = 2 ( L + B ) Divide both sides by 2

    26 / 2 = 2 ( L + B ) / 2

    13 = L + B Substract L to both sides

    13 - L = L + B - L

    13 - L = B

    B = 13 - L


    1.)

    L = 1 cm

    B = 13 - 1 = 12 cm


    2.)

    L = 2 cm

    B = 13 - 2 = 11 cm


    3.)

    L = 3 cm

    B = 13 - 3 = 10 cm


    4.)

    L = 4 cm

    B = 13 - 4 = 9 cm


    etc.
