Area and Perimeter

Perimeter is the measurement
of the outside of a shape/building
the amount of space around
a shape/building/object
how much space is around the border
Perimeter is the outline of an object

You can find the perimeter
of a shape on grid paper by
counting the squares on the border
to get the perimeter

You can also can the perimeter of
a shape by using the
formula Lx2+Wx2=Perimeter

You do not
have to put
squared after
the number

The formula of areas would be length
times width equals area

Area is the measurement of the
inside of a shape/building/object
the amount of space inside
an object
how much space is inside the shape

You can find the area of
a shape using grid paper by
counting the squares inside a
shape/building/object
to get the perimeter

You can also get the area
of a shape by using the formula
LxW=area

You have to put
squared after the
number

You can use a formula
or grid paper

Add up all the sides or use a formula
