Answer:
<h2>41.57 cm²</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- area of a regular hexagon when apothem is given:½×P×A
<h3>let's solve:</h3>
parimeter of a regular hexagon:6a
therefore
=½×[4×6]×2√3 cm²
simplify parentheses:
=½×24×2√3 cm²
simplify fraction:
=24×√3 cm²
=41.57cm²
Let's use the distance formula:

So it is:
AB :

BC:

CA:

So 9.43 + 5 + 8 =22.43
The answer to 4+5/2•2-7 is -3
