you can only find the perimeter of shapes, honey, not fractions.
They are the result of combining shapes, either by adding parts or taking parts away. We calculate the perimeter of composite shapes by splitting them into simpler pieces and then calculating the perimeter of those simpler pieces.
Congruent shapes are two shapes that are the same (angles, size perimeter/circumference)
You can't. The perimeter doesn't tell the area. There are an infinite number of shapes with different dimensions and different areas that all have the same perimeter.
