Yes ! You add al four sides to get the result
P= Add all sides A= LxW
if you add up all the sides but in a smart way
24. All you have to do to solve that is to add up all the sides when dealing with perimeters
Their perimeters are in the same ratio.
The sacle factor between two shapes is the same as the ratio of their perimeters.
All polygons
To find the perimeter of an enclosed area, you need to add the size of all of its sides. If the area is a rectangle, then you add the end, the side, the other end, and the other side.
"18 perimeters" is is a meaningless phrase since there are no units of measurement. It is like asking how tall are 18 heights?
They each have 3 interior angles that add up to 180 degrees They each have 3 exterior angles that add up to 360 degrees They each have 3 sides They are 2 dimensional shapes They have perimeters They have areas
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.
3D objects do not have perimeters.
Both will individually tessellate Both are 2 dimensional shapes Both have perimeters Both have areas Both have exterior angles that add up to 360 degrees
