The perimeter of rectangle equals 74 meters. if the length is 5 more than the width, find the width

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

The surface area would be 576 because you multiply all the numbers then multiply that number by 6
