TRANSCRIPT
Area and perimeter are different
ways of measuring a shape.
The area is the amount of space
inside the shape.
The perimeter is the distance around the edge.
This field is a rectangle.
It is 4 metres long and 3 metres wide.We can find out the area of a rectangle by multiplying the
length by the width.
4 x 3 = 12
4m
3mSo the areaof the field is
12 square metres.
We can write this as 12m2.These measurements are called the shape’s
dimensions.
Thismeans‘squared’.
Some shapes are
made by joining
two or more shapes
together. These are
called compound
(or composite)
shapes.

To find the perimeter, add the
lengths of ALL of the sides.
Make sure that you don’t miss any!
6 + 5 + 3 + 4 + 3 + 9 = 30m
To find the area, split the compound shape into smaller
shapes. Work out the area of each part and then find the total.
6x5=30m2
3x4=12m2 4m

The area of this compound shape is:
30 + 12 = 42m2.

I own a vineyard. I measure the dimensions of my fields so that I can fit in as many vines as possible.
I also work out the size of the perimeter fence.
