Place a measuring ruler or tape alongside the line. Read of the graduation marks which are next to the two points. Subtract the smaller from the larger and the result will be the length of the line segment.
When a line segment connecting two points is horizontal the length of the segment can be found by finding the absolute value of the difference in x-coordinates of the two points.
I think that you draw a square from that line, and find the area of that square.
Subtract the y-coordinates of the points and take the absolute value
It is the circumcentre of the triangle formed by the three points. Draw the perpendicular bisectors of two of the lines joining the three points. They will meet at the point that is equidistant from the three points.

To find the perpendicular distance between two points, you can use the distance formula and the concept of perpendicular lines. First, calculate the distance between the two points using the distance formula. Then, find the slope of the line passing through the two points. The perpendicular distance is the length of the line segment that connects the two points and forms a right angle with the line passing through them.
The distance formula providing you know the coordinates of its end points
Subtract the y-coordinates of the points and take the absolute value
Add the x-coordinates of the points and take the absolute value
It is the circumcentre of the triangle formed by the three points. Draw the perpendicular bisectors of two of the lines joining the three points. They will meet at the point that is equidistant from the three points.
On method would be to find the midpoint of the line segment and then to find the mid points of each of the halves.
