Lesson ObjectiveCalculate the area of shapes.

Lesson Outcomes• Correctly multiply decimals to calculate the area of at least 5

rectangles (all).• Correctly substitute numbers in a formula to calculate the area

of at least 5 circles (most).• Correctly combine the areas of 2 shapes to calculate the area

of at least 5 compound shapes (some).

Area of RectanglesUnderpinning skill = multiply pairs of numbers, particularly decimals:a) 75 x 3.4 =

b) 2.8 x 46 =

c) 115 x 2.7 =

d) 3.1 x 4.9 =

e) 6.12 x 7.3 =

Applying this skill• The rectangular banquet hall

needs new floor wood panels. It measures 28m long and 9.42m wide. What is it’s area?

263.76m²

Developing the skill.

• St. George wants a flag made so he can wave it after slaying the dragon. He wants it to be 2.3m long and 80cm high. What will its area be?

Skillswise worksheet 1

ExtensionSt. George wants a rectangular section of ground prepared for swordsmanship training: He wants the area of the space to be 60m². What could the dimensions of the training ground be?

Formula• The area for a rectangle can

be written as a formula:Area of rectangle = LW

π = value of 3.14r = radius² = squared means the value

multiplied by itself

• The area of a circle is calculated using this formula:

Area of circle = π r²

Area of circle

78.5cm²

• What is the area of this cart’s wheel? It has a radius of 5cm.

Compound Shapes

What is a‘compound shape’?

Area of a compound shape• This is the plan view of St.

George’s bedroom. What is the area of the room?

72cm²

11 cm

8 cm

6 cm

2 cm

Area of Compound Shape

• This is the draw bridge from the castle. What is its area?

6.2m

4m

Area of rectangle • 4 x 6.2 = 24.8

Area of circle• r² = 2 x 2 = 4• π r² = 3.14 x 4= 12.56

Area of semi-circle• 12.56 ÷ 2 = 6.2824.8 + 6.28 = 31.08m²
