Final answer:
The length of one section is found by dividing the total length of 6 yards by 2, which can be expressed both as (6/2) and as (6 - 6/2), making both of these expressions equivalent and correct for representing the length of one section.
Step-by-step explanation:
The question asks for two expressions that would represent the length of one of the sections when London divides his 6 yards of border evenly to create two equal sections. To find the length of one section, you would take the total length of the border (6 yards) and divide it by 2, since there are two sections. Therefore, the length of one section is (6/2) yards. Alternatively, we can express the same length by subtracting half of the total length from the total length, which is also (6 - 6/2) yards. Hence, both expressions (6/2) and (6 - 6/2) give us the length of one section.
