The best design for this experiment would be a repeated measures design. This is ideal to determine if eating an apple makes you healthy.
<h3>What is an experimental design?</h3>
An experimental design refers to the general structure of an experiment including how people are distributed into the control and experimental group to test a specific phenomenon.
<h3>What is a repeated measures design?</h3>
In a repeated measures design all participants are both parts of the control group, in this case, people who do not eat apples, and the experimental group, or people who eat apples.
<h3>What does this design imply?</h3>
In the case of determining if eating an apple every day, this design implies:
- All participants will be asked to not eat apples every day for a specific period such as one or two months, and health levels will be measured during this time.
- After the first step, all participants will be asked to eat an apple every day during the period, and their health will be measured.
- The researcher can compare the results of each participant, which is more accurate than comparing one participant to another.

Answer:
Length =40 ft.
width. = 8 ft.
Step-by-step explanation:
If The length is five times the width , then
width = w
length = 5w
Perimeter of Rectangle = 2( l+b)
2(5w+w)= 96
2( 6w) = 96
12 w= 96
w = 96/12
w= 8ft.
length = 5(8)
= 40 ft
