Answer:
L=W+8
Explanation:
This means that whatever number of centimeters the width is, you will always add 8 centimeters in order to reach the size of the length. In order to calculate the perimeter of the rectangle you have to add all its four sides and the final formula would be as follows:
W+W+L+L=P, where W is Width and L, is Length (W+8).
In other words, you can calculate as shown below:
W+W+(W+8)+(w+8)=P
