Question

Find the area of a hexagon with sides of length 12 cm

Answer 1

The answer is 374 cm²

Area (A) of a hexagon with side a is:
$A= \frac{3 \sqrt{3} }{2} a^{2} \\ \\ a = 12cm \\ \\ A= \frac{3 \sqrt{3} }{2} 12^{2} \\ \\ A= \frac{3 \sqrt{3} }{2} *144 \\ \\ A =\frac{3 *1.73}{2} *144 \\ \\ A = 373.7 cm^{2}$
A ≈ 374 cm²
