Perimeter

Perimeter

The formula of perimeter would be
length plus width times two

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

Area

Area

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
