This is used to generate the Length of the perpendicular from point(x1, y1) to the line Ax + By + C = 0.
Find the length of the perpendicular from the point (4,3) on the line
x + 2y + 5 = 0.
x1 = 4,
y1 = 3,
A = 1,
B = 2,
C = 5
Substitute in the formula as
Length of the perpendicular = 3
The above example will clearly illustrates how to calculate the Perpendicular Length/Distance manually.
