Use a centimeter ruler and a separate sheet of paper to draw an 8cm by 6cm rectangle. List its perimeter on the table below. Use your two pieces to create 4 new geometric shapes. After making each shape, determine its perimeter.

perimeter = the sum of the all the sides

8cm +6cm+8cm+6cm = 28cm

Wait what?

To draw an 8cm by 6cm rectangle using a centimeter ruler and a separate sheet of paper, follow these steps:

1. Place the sheet of paper on a flat surface.
2. Take the centimeter ruler and align it vertically along one edge of the paper.
3. Starting from one end of the ruler, mark a point at the 8 cm mark on the paper.
4. Align the ruler horizontally from the marked point, and make another mark at the 6 cm mark on the ruler.
5. Connect the marked points with straight lines using a pencil or pen to form a rectangle.

Now, let's calculate the perimeter of the rectangle.

The perimeter of any shape is the sum of the lengths of all its sides. In this case, since the rectangle has two pairs of parallel sides, we can calculate the perimeter by adding the lengths of the opposite sides.

The length of the rectangle is 8 cm, and the width is 6 cm. Therefore, the opposite sides of the rectangle have the lengths 8 cm and 6 cm. Adding these lengths gives us:

Perimeter = 8 cm + 6 cm + 8 cm + 6 cm = 28 cm

So, the perimeter of the 8cm by 6cm rectangle is 28 cm.

To create 4 new geometric shapes with the given pieces, here are a few possibilities:

1. Triangle:
- Use one side of the rectangle as the base.
- Connect the endpoints of the base to the opposite corner of the rectangle.
- Calculate the lengths of the sides of the triangle and add them to find the perimeter.

2. Square:
- Cut the rectangle into equal parts.
- Take two parts and align them to form a square.
- Calculate the lengths of the sides of the square and add them to find the perimeter.

3. Rhombus:
- Cut the rectangle diagonally to form two triangles.
- Arrange the triangles so that their bases are parallel.
- Connect the opposite endpoints to form a rhombus.
- Calculate the lengths of the sides of the rhombus and add them to find the perimeter.

4. Trapezoid:
- Cut the rectangle diagonally to form two triangles.
- Arrange the triangles so that the bases are non-parallel.
- Connect the remaining endpoints to form a trapezoid.
- Calculate the lengths of the sides of the trapezoid and add them to find the perimeter.

For each of these shapes, follow the same process as before to measure and calculate the perimeters using the centimeter ruler and the separate sheet of paper.
