Worked examples

Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   A rectangle is 6 m long and 4 m wide. What is its area in square meters?

   1. Area is the space inside a rectangle. Multiply its length by its width.
   2. Area = length × width = 6 × 4 = 24 square meters.

   Answer: 24

2. Example 2

   What is the most specific name for the quadrilateral shown?

   1. Both pairs of opposite sides are parallel, so it is a parallelogram.
   2. It has no right angles, so it is not a rectangle, and its sides are not all the same length, so it is not a rhombus.
   3. Its most specific name is parallelogram.

   Answer: parallelogram

3. Example 3

   I am a quadrilateral with 4 right angles and 4 sides that are all the same length. What is my most specific name?

   1. It has 4 right angles (square corners), so it is a rectangle.
   2. All 4 sides are the same length, so it is also a rhombus.
   3. A rectangle that is also a rhombus is a square — its most specific name is square.

   Answer: square
