Geometric mean

Calculate the geometric mean of numbers a=15.2 and b=25.6. Determine the mean by construction where a and b are the length of the lines.

Correct answer:

m =  19.7261

Step-by-step explanation:

$$\begin{gathered} a=15.2 \\ b=25.6 \\ m=\sqrt{a\cdot b}=\sqrt{15.2\cdot 25.6}=19.7261 \end{gathered}$$
