So if a person has 1/8 of a pitcher then you have 8 people per pitcher. Then if you have 5 pitchers you do 5 x 8 and get 40 so 40 people will be served. Hope this helps :)
Find the area of the rectangle. You can find the area of a rectangle with the following formula:

w = width, and l = length.
Plug in your width and length:

The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:

The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:
The answer is 12. if you need help, do 60•.2
