Example Question #1 : How To Find The Length Of A Side In Other Polygons
The perimeter of a regular octagon is one mile. Give the sidelength in feet.
One mile is equal to 5,280 feet, so divide this by 8:
Example Question #2 : How To Find The Length Of A Side In Other Polygons
What is the sidelength, in feet and inches, of a regular octagon with perimeter feet?
feet is equivalent to inches. Each side of a regular octagon, an eight-sided figure, measures one-eighth of this:
Each side of an octagon with perimeter feet measures
this is equal to .
Example Question #3 : How To Find The Length Of A Side In Other Polygons
In a septagon, each of the sides are equal to one another. If the perimeter is feet, what is the length of one of the sides?
If the perimeter of a septagon, in which each side is equal to the other, is 98, the length of each side will be 7 feet because 98 divided by 7 is 14.
