Answer 1

= 21

Answer 2

Because the regular hexagon formed is formed by 6 equilateral triangles of side 7, the area of the regular hexagon can be found by multiplying 6 times the area of one equilateral triangle.

The area of an equilateral triangle can be found by the formula: [ (side)² * √ 3 ] / 4.
[ (7)² * √ 3 ] / 4 = ( 49 √ 3 )/ 4

The area of the regular hexagon is: 6 * { ( 49 √ 3 )/ 4 } = 3 * { ( 49 √ 3 )/ 2 =
73.5 √ 3 ---> Option 1
