ANSWER


2.29m

Step-by-step explanation

The combined height of the three people is 7 meters. This means that the sum of their heights is 7 meters.

Joey is 2.31 m tall and Eli is 2.4 m tall.

Let Keith's height be k.

Therefore, we have that the sum of their heights is:


2.31+2.4+k=7

Solve for k:


\begin{gathered} 4.71+k=7 \\ k=7-4.71 \\ k=2.29m \end{gathered}

hence, Keith is 2.29 meters tall.
