Area is the amount of space occupied by a two-
dimensional figure. In other words, it is the quantity
that measures the number of unit squares that cover
the surface of a closed figure. The standard unit of
area is square units.

P E R I M E T E R
The perimeter of a shape is defined as the total
distance around the shape. It is the length of the
outline or boundary of any two-dimensional geometric
shape. The perimeter of different figures can be
equal in measure depending upon the dimensions.
