<h3>What is Geogebra Tools?</h3>
Geogebra tools are software which is used to study an absolute geometry with zero errors.
Since, Geogebra contains various tools, In part b we have drawn a square through polygon command. Its allows to select the number of sides, so we select 4 cause square requires 4 equal sides.
Now, we very it in c part just by drawing a 4 connected lines which have 90° adjacent angles.
Here, by comparing their geometry it seems identical
Thus, the result, in part b and c matches for each other.

Step-by-step explanation:
Given
less than the most hour
Required
Hours read by Miss Allen
The question is incomplete, as the hours read by each student is not given.
To solve this, I will assume that the longest hours read by a student is x.
So, the expression for Miss Allen will be:

Assume that 
The expression becomes

Take LCM and solve


9pi/8 = 8pi/8 + pi/8 = pi + pi/8
12 + pi - 9pi/8 = 12 + pi - pi - pi/8
