Question 133635
Find the perimeter of the regular polygon: 
regular hexagon with sides 28.5 millimeters long.

A hexagon has 6 sides.

If each side is 28.5mm, then 6 sides times 28.5mm will give us the perimeter.

Let P = perimeter.

P = 6 times 28.5

P = 171mm

NOTE: You can also add 28.5mm SIX TIMES and still get the same perimeter.

Here it is:

P = 28.5mm + 28.5mm + 28.5mm + 28.5mm + 28.5mm + 28.5mm

P = 171mm

Either way, the answer is 171mm.

Of course, applying multiplication is FASTER!
