We have been given five-number summary. We are asked to find the number of years of experience that 25% of Carlson High School teachers have.

We know that 1st point of 5 number summary represents lowest data point, 2nd point represents 1st or lower quartile, 3rd point represents median, 4th point represents upper quartile, and 5th point represents highest data point.

We know that lower quartile represents 25% of data. We can see that the value of lower quartile is 5.

Therefore, 25% of Carlson High School teachers have fewer than  5 years of experience.

p=4s−10 inches

let's say that the rectangle has sides  a  and  b.

you already know that  a=s−6  and  b=s+1.

the perimeter of a rectangle is

p=2⋅(a+b)=2(s−6+s+1)=4s−10
