James and Sylvie need to paint the line around the outside of a soccer field. To know how much paint to buy, they must find the perimeter of the field.

James claims, “I can calculate the perimeter of the field by using the formula P = 2(l + w).”

Sylvie replies, “That’s not right, James. The correct formula is P =2l+ 2w.”

• Who is correct? Is it possible for both to be right? Provide evidence to support your answer.
