The perimeter of a regular hexagon of side 8 cm is:

  • A.47 cm
  • B.48 cm
  • C.49 cm
  • D.50 cm

Answer: B

The perimeter is 48 cm.

A regular hexagon has six equal sides, so its perimeter is six times the side.

\[ 6\times8=48\text{ cm} \]

47, 49 and 50 cm are not six times 8.

A regular hexagon has six equal sides and six equal angles of 120 degrees each. Its perimeter is the sum of all six sides, 8 + 8 + 8 + 8 + 8 + 8 = 48 cm. The area would use a different formula, which is not needed here.
