Help please will medal. Don't understand how to solve. Three sides of a hexagon have a length of 14 cm each. Each of the remaining three sides has a length of 18 cm. What is the perimeter of the hexagon? A.252cm B.96cm C.78cm D.64cm

OpenStudy (td5):

To gain the perimeter of any polygon, you must add all of the sides of the polygon together. For this, we can use simple math to find the full perimeter. Since we know three sides ot the hexagon are 14 cm each, we can multiple 14 by 3. A hexagon has six sides in total, so there are three remaining sides. We can multiply 18 by 3 to gain the remaining sides together. \[14\times3 + 18\times3\]

OpenStudy (td5):

The final step(s) is to use the order of operations to solve the equation, giving you the perimeter of the Hexagon in centimeters.
