    The perimeter of the rectangle is calculated using the following rule:

    perimeter = 2 (length + width)

    We are given that:

    perimeter = 74 meters ... > given I

    length is 5 more that width.

    This means that:

    length = width + 5 ... > given II

    Substitute with given I and given II to get the width of the rectangle as follows:

    74 = 2 (width+5+width)

    74/2 = 2*width + 5

    37 = 2*width + 5

    37-5 = 2*width

    32 = 2*width

    width = 32/2 = 16 meters

    If you want to get the length, we can use given II as follows:

    length = width + 5

    length = 16 + 5 = 21 meters

    Based on the above calculations:

    width of rectangle = 16 meters

    length of rectangle = 21 meters
