Answer:
Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> says that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the third side
so
in this problem
Applying the midpoint theorem
The expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.
<h3>What is the perimeter of a square?</h3>The measure of the boundary of the sides of a square is called its perimeter. The perimeter of a square is 4 times the side of the square.
Here, (<em>a</em>) is the side of the square.
A square has a perimeter of 12x +52 units. The perimeter of a square is 4 times the side of the square. Thus, the side of this square is,
Thus, the expression which represents the side length of the square which has perimeter of 12x 52 units is 3x+12 units.

In these types of tables, the final box, bottom rightmost, is always the main total. This total will always add up to the same number whether you add the column or the row.
Let find it for this problem.
We can get the grand total from adding the 2 number from the row or the column.
<em>If we add column, we get, .</em>
<em>If we add row, we get, .</em>
So, our total is 166. 166 people were polled.
ANSWER: 166 People
