1. Find all of the missing sides of the irregular shape by either:
- comparing parallel sides
- breaking the shape down into smaller shapes
2. Find the sum of all of the outside edges.
1. Break down the irregular shapes into smaller shapes.
2. Find the edges of the smaller shapes.
3. Calculate the area of each small shape.
4. Add all of the areas of the small shapes (the sum will be the area of the irregular shape).
how dont u people get this i get it easily and im 13
I can not seem to understand how this works call me dumb but I don't remember doing this and my daughter needs help
I don't understand how to make the perimeter!!.......
break the shape into rectangles and then find the area for each rectangle. (length x width) then add all area's together. Don't forget to label with squared.
find all of the units of the shape and add them up
tip to remember what to do for area or perimiter:
when you see perimiter remember that you add all the sides a a way to remember that is there is a "T" in the word perimiter and it looks like a addition sign
how do you find it ?!??!? i mean like what about a triangle . how do you find the area and the perimeter of it ? you know the little squares some of them are not all completely fillled in . do we just measure it with a ruler or something ? please answer .
Triangles are similar to rectangles for finding the area. You still multiply length times width but since it takes 2 triangles to make a rectangle divide the area by 2. This will give you the area of a triangle

"Examples of area are essential here. Also some examples with circles or parts of circles would be good."
