Solution:

Concept:

To simplify, find the square roots of decimal numbers by converting them to fractions or using perfect squares.

Explanation:

First, determine the square root of 23.04. Since

4.8^2 = 23.04

, we have

\sqrt{23.04} = 4.8

Next, find the square root of 86.49. Since

9.3^2 = 86.49

, we have

\sqrt{86.49} = 9.3

Now add:

4.8 + 9.3 + 9.3 = 4.8 + 18.6 = 23.4
