What is the difference between an area and perimeter?

area is................ length x width perimeter is .......... length x width x length x width * * * * * WRONG. Area is the amount of space occupied by a shape. In the case of a rectangle, it is length x width, as stated above. But that does not work for circles, ellipses, triangles, other quadrilaterals and polygons and many other shapes, all of which have areas. A perimeter is the sum of all the lengths bordering the shape. The perimeter of a rectangle is NOT length x width x length x width but their sum! But again, that does not work for most other shapes.
