Find the area $A$ of a hexagon if short diagonal $s = 8 cm$ .

Answer

$323 cm^{2}$

Explanation

STEP 1: find side $a$

To find side $a$ use formula:

s = 3 \cdot a

After substituting $s = 8 cm$ we have:

8 cm = 3 \cdot a

a = \frac{8 cm}{3}

a = \frac{8 3}{3} cm

STEP 2: find area $A$

To find area $A$ use formula:

A = \frac{3 3 \cdot a ^{2}}{2}

After substituting $a = \frac{8 3}{3} cm$ we have:

A = \frac{3 3 \cdot ( \frac{8 3}{3} cm ) ^{2}}{2}

A = \frac{3 3 \cdot \frac{64}{3} cm ^{2}}{2}

A = \frac{64 3 cm ^{2}}{2}

A = 323 cm^{2}
