What is the area of a regular hexagon if a side is 30

sergij07 [2.7K]

<h3>Answer:</h3>

$1350\sqrt{3}$ square units (approximately 2338.26859)

<h3>Step-by-step explanation:</h3>

The formula for finding the area of a regular hexagon when you know its side length is $A=\frac{3\sqrt{3}*s^2}{2}$ , where $A$ is the area and $s$ is the side length.

Substitute in the side length. $A=\frac{3\sqrt{3}*30^2}{2}$
Simplify the exponent. $A=\frac{3\sqrt{3}*900}{2}$
Multiply. $A=\frac{2700\sqrt{3}}{2}$
Divide. $A=1350\sqrt{3}$

$1350\sqrt{3}$ is as simple as the solution can get without estimating, but you can estimate with a calculator to find that it is approximately 2338.26859.
