Split it up
small square on top with side legnths s and s
big squaer with legnth and width 5s and 3s
area=legnth times width
total area=5s*3s+s*s=15s^2+s^2=16s^2
toatl area=600
600=16s^2
divide both sides by 16
37.5=s^2
squer root both sides6.12372
tenth
6.1 mm is s
s=6.1mm

Answer:
At least one student is 23: Must be true
Some students are younger than 15: Could be true
Step-by-step explanation:
Statement 1: A median is a number in the middle for ex. 1, 2, 3, 4, 5 in this example 3 is the median. Another ex could be 1, 2, 3, 4, 5, 6. This time you would have to add (3 + 4), divide by 2, which equals 3.5.
Since there are 21 students in class making it an odd number 23 must be true.
Statement 2: Based on the information I am given, I would say could be true because the difference between the oldest and the median is 29 - 23 = 6 so it could be true.
