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
