Which book needs more space? The Atlas needs more space because it has a bigger surface.
Which shape needs more space? The yellow one needs more space.
Which object needs more space? The amount of surface covered by the blackboard is called the area. BlackboardStudent’s desk
Which shape has the larger area? Sometimes it is difficult to tell. So what do we need to do?
We can use small squares to cover small objects. We can use sheets of newspaper to cover larger surfaces.
The area of the shape can be found by ticking the square as each one is counted. How can we find the area of a shape which has been drawn on squared paper?
Area = _____ square units. 12
Area = _____ square units. 16
Area = _____ square units. 20
Area = _____ square units. 24
Find the area of these shapes. Different shapes can have same area.
Shapes can be made up of whole squares and half squares. Two halves make up one whole square.
whole half Letter E has 15 whole squares and 1 half square. Area = 15 ½ square units
Letter A has: whole 14 whole squares half 2 half squares (2 halves make 1 whole square) Area = square units = 15 square units
This shape has: whole 20 whole squares half 12 half squares (2 halves make 1 whole square) Area = square units = 26 square units 12 half squares = 6 whole squares
Area = _____ square units. ___ whole squares + ___ half squares
Area = _____ square units. ___ whole squares + ___ half squares
Area of letters and shapes can be found by using the nailboard.
To take measurements we can use the: metre ruler measuring tape trundle wheel ruler
1 square represents 1 cm Area = _____ square centimetres. 26
1 square represents 1 cm Area = _____ square centimetres. 26 ___ whole squares + ___ half squares 244
1 square represents 1 cm Area = _____ cm Area= 6.5 cm x 4 cm = 26 cm 2
length breadth Area = length x breadth
11 cm 7 cm Area = length x breadth = 11 cm x 7 cm = 77 cm 2
