A classroom table is 1 m wide and 1.75 m long. How many 39 cm wide chairs can fit around the table?

    to do this, you get the perimeter of the table.
    recall that the perimeter of a rectangle is given by,
    P = 2*L + 2*W
    where
    L = length
    W = width
    substituting,
    P = 2(1.75) + 2(1)
    P = 3.5 + 2
    P = 5.5 meters
    then we convert this to centimeters. note that
    1 meter = 100 centimeters
    therefore 5.5 m = 550 cm
    finally we divide 550 by 39 to get the number of chairs that could fit:
    550/39 = 14.102
    but since there is no 'decimal' chairs, we only take the whole number which is 14 chairs.

    hope this helps~ :)
