The calculated area of the regular hexagon, using the formula A = 3√3/2 * s² with a side length of 11 units, is approximately 314.4 u², confirming the given value. Here option B is correct.
The formula for the area of a regular hexagon is A = 3√3/2 * s², where s is the length of one side.
Plugging in 11 for s, the area of the regular hexagon is A = 3√3/2 * 11².
Simplifying the expression, the area of the regular hexagon is A = 3√3/2 * 121.
Multiplying the numbers, the area of the regular hexagon is A = 363√3/2.
Using a calculator, the area of the regular hexagon is approximately A = 314.4 u². Here option B is correct.
