Tuesday, Feb 11 Chapter 9.6 Area of Composite Figures
Slide 12
Objective: To find the area of composite figures.
Slide 13
Area of Composite Figures At the end of this lesson you should
be able to answer the following question. How do you decompose
figures to find the area?
Slide 14
Area of Composite Figures A composite figure is made up of two
or more two-dimensional figures.
Slide 15
Area of Composite Figures Can we find the exact area of the
polygon below?
Slide 16
Area of Composite Figures Can we find the exact area of the
polygon below? What if we divided the polygon into two figures we
know? What is the bottom figure?
Slide 17
Area of Composite Figures Can we find the exact area of the
polygon below? What if we divided the polygon into two figures we
know? What is the bottom figure? A rectangle. What is the top
figure?
Slide 18
Area of Composite Figures Can we find the exact area of the
polygon below? What if we divided the polygon into two figures we
know? What is the bottom figure? A rectangle. What is the top
figure? A trapezoid. What is the area of each figure?
Slide 19
Area of Composite Figures
Slide 20
Find the area of the figure below. Can we divide the figure
into two known figures?
Slide 21
Area of Composite Figures Find the area of the figure below.
Can we divide the figure into two known figures? What is the area
of each figure?
Slide 22
Area of Composite Figures
Slide 23
Find the area of the figure. Do this on your own.
Slide 24
Area of Composite Figures
Slide 25
Find the area of the figure. Do this on your own.
Slide 26
Area of Composite Figures
Slide 27
Find the area of the figure. To find the area of overlapping
figures, add the areas of the figures if they were not overlapped
and then subtract the overlapped area.
Slide 28
Area of Composite Figures Find the area of the figure. What is
the area of the square?
Slide 29
Area of Composite Figures Find the area of the figure. What is
the area of the square? A = 12 12 = 144cm
Slide 30
Area of Composite Figures Find the area of the figure. What is
the area of the square? A = 12 12 =144cm What is the area of the
rectangle?
Slide 31
Area of Composite Figures Find the area of the figure. What is
the area of the square? A = 12 12 =144cm What is the area of the
rectangle? A = 12 15 = 180cm What is the area of both figures?
Slide 32
Area of Composite Figures Find the area of the figure. What is
the area of the square? A = 12 12 =144cm What is the area of the
rectangle? A = 12 15 = 180cm What is the area of both figures?
144cm+180cm=324cm
Slide 33
Area of Composite Figures Find the area of the figure. What is
the area of the overlapped area? What is the area of both figures?
144cm+180cm=324cm
Slide 34
Area of Composite Figures Find the area of the figure. What is
the area of the overlapped area? A = 7 6 =42cm What is the area of
both figures? 144cm+180cm=324cm What is the total area?
Slide 35
Area of Composite Figures Find the area of the figure. What is
the area of the overlapped area? A = 7 6 =42cm What is the area of
both figures? 144cm+180cm=324cm What is the total area? 324cm -
42cm = 282cm
Slide 36
Area of Composite Figures Find the area of the figure. Do this
on your own.
Slide 37
Area of Composite Figures Find the area of the figure. Area of
the top rectangle A = 6 7 =42ft Area of the bottom rectangle. A = 6
8 = 48ft Overlapped area. A = 5 5 = 25ft Total area is 42ft + 48ft
- 25ft = 65ft
