Step 1

Find the area of one equilateral triangle

Applying the law of sines

$Area=\frac{1}{2} *a*b*sin C$

in this problem

a=b=7 cm

C=60 degrees

so

$Area=\frac{1}{2} *7*7*sin 60$

$Area=\frac{1}{2} *49*\frac{\sqrt{3}}{2} \\ Area=49*\frac{\sqrt{3}}{4}$ cm²

Step 2

To calculate the area of the hexagon multiply the area of one equilateral triangle by $6$

$Area Hexagon=6*[49*\frac{\sqrt{3}}{4}] \\ Area Hexagon=73.5*\sqrt{3}$ cm²

therefore

the answer is the option

73.5 sqrt 3cm²

√10 Multiple √15 is equal to

Paul [167]

$\\ \sf\longmapsto \sqrt{10}\times \sqrt{15}$

$\\ \sf\longmapsto \sqrt{10\times 15}$

$\\ \sf\longmapsto \sqrt{2\times 5\times 3\times 5}$

$\\ \sf\longmapsto \sqrt{5\times 5\times 6}$

$\\ \sf\longmapsto 5\sqrt{6}$

None of the above should be 4th option
