2. The distance
around the
outside of a shape
is called the
perimeter.
8 cm
6 cm
8 cm
6 cm
The perimeter of the shape is 8 + 6 + 8 + 6 = 28cm.
First we need to find he length of each side by
counting the squares.

3. What is the perimeter
of each of these
shapes? Your teacher
will give you copy of
the worksheet.

5. The area of a
shape is the
amount of space
inside it.
The area of the shape is 18cm

.
To find out how much shape is inside we can
count the squares.

7. To find the area of
an irregular shape
you first count the
full squares inside
it.
This is an irregular
shape. This
means that the
sides aren’t
straight.

8. You then count all
the other squares
which have more
than half the area
covered.
The area of the shape is 60cm

.

10. Counting each
square can take a
long time. Does
anyone know a
quicker way?
The area of the shape is 48cm

.
The rectangle is made of 6 rows of 8 squares.
To work out the number of squares
we times 6 by 8.

12. We can work out the area of a rectangle
without the grid.
length

Area = length x width

13. Now work out the
area of these
rectangles.
They are not
drawn to scale.

14. A shape that is
made from other
shapes is known
as a composite
shape.
To find the area of
this shape we
have to split it up
into two
rectangles.
