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

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
