give me answers for all of the questions

Question 1: Use page 4 of 13
How do you find the length of a side joining points when the second coordinates (y-coordinates) are the same?

Question 2: Use page 4 of 13
What is the distance, in centimeters, between points with coordinates (−7,20) and (−26,20)?

Question 2: Use the coordinate plane below to solve the problem . Also use page 8 of 13 for help.

A room is mapped with coordinates:
A (5,–2), B (–5,–2), C (–5,7), and D (5,7).

Each unit of the coordinate plane represents a meter. Find the number of meters of crown molding needed to place around the room (perimeter).

Answer for Question 1: When the y-coordinates are the same, you can find the length of the side by subtracting the x-coordinates of the two points.

Answer for Question 2: The distance between points (-7,20) and (-26,20) is 19 centimeters.

Answer for Question 3: The perimeter of the room is 28 meters.
