A, B, C, D are points on a line.
AB = 1
BC = 2
CD = 4

Find the length of segment AD. Consider all possibilities.
So far, I've only gotten 7, 5, and 1. But I know there is one left. Can you guys help?

The points A, B, C and D are collinear points

The length of the segment AD is 7 units

How to determine the length AD?

The given parameters are:

AB = 1

BC = 2

CD = 4

Because the points are on the same line, then the following is the possible equation

AD = AB + BC + CD

Substitute known values

AD = 1 + 2 + 4

Evaluate the sum

AD = 7

Hence, the length of the segment AD is 7 units
