Final answer:
To find the length of each section in the garden, divide the total length of the garden by the number of sections. The length of each section is 1.7 yards.
Step-by-step explanation:
To find the length of each section in the garden, we need to divide the total length of the garden by the number of sections. The garden is 81/2 yards long, which is equivalent to 8.5 yards. If each section is equal in length, we can divide the total length by the number of sections to find the length of each section. So, 8.5 yards divided by the number of sections is the length of each section in yards.
To determine the number of sections, we can use the given information that each section is equal in length. Since the options provided in the question are all in yards, we can assume the sections are whole yards. Thus, we need to find a number that divides evenly into 8.5 yards.
Dividing 8.5 by 1 gives a remainder of 0.5, which means it is not a whole number of sections. Dividing 8.5 by 2 gives a remainder of 0.5, which means it is still not a whole number of sections. Dividing 8.5 by 3 gives a remainder of 2.5, which is also not a whole number of sections. Dividing 8.5 by 4 gives a remainder of 0.5, which again is not a whole number of sections.
Therefore, dividing 8.5 by 5 does not result in a remainder, which means it is a whole number of sections. So, each section is 8.5 yards divided by 5, which equals 1.7 yards.
