To find out how much ribbon Harlotte needs to decorate the octagon, we first calculate the perimeter of the octagon. Since each side measures 9.58 cm and there are 8 sides in an octagon, the total perimeter is 8 times 9.58 cm, which equals 76.64 cm. Therefore, Harlotte needs 76.64 cm of ribbon to decorate the edge of the box.
If you know the perimeter, there is no need to find it again.
To find the perimeter you add and to find the area we multiply.
The perimeter of a triangle is the distance around it. Add the lengths of the three sides to find the perimeter.
perimeter of what quadrant?
what is the perimeter of a pentegon?
Find the distance of each side and add to find the total perimeter.
you can only find the perimeter of shapes, honey, not fractions.
You find perimeter by adding all the sides of a figure.
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!

There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
