The document provides information about calculating the areas of different shapes using squares or square units. It includes examples of finding the areas of rectangles, triangles, letters of the alphabet, and irregular shapes by counting whole and half squares. Various area formulas are presented, such as Area = length x breadth. Word problems demonstrate calculating areas of real-world objects like fields, stadiums, and ponds.

2. Which book needs more space?
The Atlas needs more space because it
has a bigger surface.

3. Which shape needs more space?
The yellow one needs more space.

4. Which object needs more space?
Blackboard Student’s desk
The amount of surface covered by
the blackboard is called the area.

5. Which shape has the larger area?
Sometimes it is difficult to tell.
So what do we need to do?

6. We can use small
squares to cover
small objects.
We can use sheets of
newspaper to cover
larger surfaces.

7. How can we find the area of a
shape which has been drawn
on squared paper?
The area of the shape
can be found by ticking
the square as each one
is counted.

8. 12
Area = _____ square units.

9. 16
Area = _____ square units.

10. 20
Area = _____ square units.

12. Find the area of these shapes.
Different shapes can have same area.

13. Shapes can be made up of whole
squares and half squares.
Two halves make up one whole square.

14. Letter E has 15
whole squares and
1 half square.
Area = 15 ½ square units

15. Letter A has:
14 whole squares
2 half squares
(2 halves make 1 whole square)
Area = 14 + 1 square units
= 15 square units

16. This shape has:
20 whole squares
12 half squares
(2 halves make 1 whole square)
12 half squares = 6 whole squares
Area = 20 + 6 square units
= 26 square units

17. 20 4
___ whole squares + ___ half squares
22
Area = _____ square units.

18. 16 6
___ whole squares + ___ half squares
19
Area = _____ square units.

19. Area of letters and shapes can
be found by using the nailboard.

20. To take measurements we can
use the:
• metre ruler
• measuring tape
• trundle wheel
• ruler

21. 1 square represents 1 cm
26
Area = _____ square centimetres.

22. 1 square represents 1 cm
24 4
___ whole squares + ___ half squares
26
Area = _____ square centimetres.

23. Area= 6.5 cm x 4 cm
= 26 cm2
1 square represents 1 cm
26
Area = _____ cm2.
