area: multiply length times width for rectangles

Perimeter and area are not sufficient to determine the shape of a figure.
Area is the amount of square units in a 2-D shape, and perimeter is the distance around a shape
You have to add all the sides of the shape .
Line
You break it up into smaller shapes which are less irregular. If these are more regular, you can calculate their contribution to the perimeter, and their area. You can then add these together.
No, you can not calculate an area if you know just the perimeter. For example, rectangle with sides of 10 and 20 would have a perimeter of 60 and an area of 200, but a square of sides 15 would have a perimeter of 60 and an area of 225. You need to know more details about the shape than just the perimeter.
perimeter is when you have a shape and then you have your area and that is what is in the middle of the shape and perimeter is the edge of the shape.

No , perimeter is the measurement outside of the shape; the border. Area is the measurement of inside of the shape.

No, the area will get smaller, not the perimeter.

Line
The perimeter is the outside of a shape and the area is the inside of it
If you want to enclose a certain area, the shape that does it with the shortest perimeter is a circle.
