The numerical length of BD is 20.
We have a Line Segment BD and a point C on it.
We have to determine the numerical length of BD.
A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
According to question, we have -
BD = 5x
BC = 4x
CD = 4
Now,
BD = BC + CD
5x = 4x + 4
x = 4
Therefore - BD = 5x = 5 x 4 = 20
Hence, the numerical length of BD is 40.
