Lesson 3: Surface Area of Other Composite Shapes
From lesson 1 remember the surface area of prisms and cylinders is the sum of all visible
sides.
Example 1: Determine the surface area of this object.
Lesson 6: Square Roots and Perfect Squares
A living room is a square with area 400 m2. What is the side length of the room?
To find this we can take the square root of the area. The same can be done i

Lesson 1: Scale Diagrams, Enlargements, and Reductions
A diagram that is an enlargement or a reduction of another diagram is called a scale
diagram. Here is a letter F and a scale diagram of it.

Lesson 3: Surface Area of Composite Shapes
An object that is made up of, or composed, of other objects is called a composite object.
To determine the surface area of a composite object we can draw net
Lesson 1: Modelling Polynomials
A polynomial is one term or the sum or difference of terms whose variables have wholenumber exponents.
Terms are numbers, variables, or the product of numbers and varia
Lesson 1: Review of Surface Area
The surface area of a shape is the area of all visible surfaces. There are several shapes we
can determine the surface area of.
A. Surface Area of Prisms

Lesson 2: Similar Polygons and Triangles
A polygon is a closed shape that consists of line segments. For example, triangles and
squares are polygons.
When one polygon is an enlargement or reduction of
