the term used for the perimeter of a circle.
3m
5m

Area - the area is the size of a surface.
5m
4m
3m
(not to scale)
4m
Area = width x height
The width is 5m and the height is 3m so
The area of the rectangle is 5m x 3m = 15m²
(not to scale)
The width and height are the same size.
The area of the square is 4m x 4m = 16m²
