2. Area and
Volume of
Solids
- Area of Triangles
- Area = 1/2 b x h
- h = The Hight of the
Triangle = the distance
between the top and
bottom of the middle.
- Can be called Altitude
- Can be called Altitude
- b = The Width of the
Triangle = the distance
between the left and right
corners of the bottom side.
- h = The Hight of the
Triangle = the distance
between the top and
bottom of the middle.
- The Area of a Triangle is
basically the Width x Hight, and
that would be devided by a
half.
- Area = 1/2 b x h
- Area of a Parallelogram
Area = b x h
- Area of a Rhombus and Kite
Area = 1/2 (b x h)
- Area of a Trapezium
- First off you would devide your
Trapezium into two Triangles,
making sure that the deviding
line goes from the bottom left
corner to the top right corner.
Then you would use the
Triangles Are Formulae
- Triangle 1 Area = 1/2 (a x h)
- A being the width for that Triangle.
- A being the width for that Triangle.
- Triangle 2 Area = 1/2 (b x h)
- B being the width for that Triangle.
- B being the width for that Triangle.
- And to bring it
all together to
work out the
area of the
Original
Trapezium, you
just ass both of
the answers
together
- Or you can just use the Formula
- Trapezium Area = 1/2 (a+b) x h
- A being the
Width for
Triangle 1
- B being the
Width for
Triangle 2
- A being the
Width for
Triangle 1
- Trapezium Area = 1/2 (a+b) x h
- Or you can just use the Formula
- First off you would devide your
Trapezium into two Triangles,
making sure that the deviding
line goes from the bottom left
corner to the top right corner.

Triangles Are Formulae
- Composite Areas
- When it comes to
the Area of
Composite Shapes
(Shapes that are
not a set shape like
a Square and are
made up of 2 or
more shapes)
- The best bet would be
to simpily break up the
Composite Shape into
the different base
shapes, and then work
out the Area by finding
the Area of EACH
shape and adding
them all together.

(Shapes that are

- Area of Squares
- Area = b x h
- Simple really..
- Area = b x h
- Volume of Solids
- Volume = Area of Cross Section x Length
- Find the AREA of the
shape and times that
by the length of the
Object, assuming
that it is the same
shape all the way
down/across
- Volume = Area of Cross Section x Length
- Surface Area
- The SURFACE area of lets say a
cuboid is just simply the area of
all the sides added together.
- The Net for a cuboid
is just each side's
area, but placed down
as if you were going to
glue each side
together to make a 3D
object.
- The SURFACE area of lets say a
cuboid is just simply the area of
all the sides added together.
