Answer:

The perimeter of the polygon = 18 units

The area of the polygon will be square units

Step-by-step explanation:

Computing the Perimeter of the Polygon:

Considering the polygon with vertices

• W (11,2)

• X (11,8)

• Y (14,8)

• Z (14,2)

As the polygon is drawn in coordinate plane as shown in figure a.

From the attached figure a, we can observe that

• The length of the side units

• The length of the side units

• The length of the side units

• The length of the side units

So, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.

The perimeter of the polygon =

                                                  = 3 + 6 + 6 + 3

                                                  = 18 units

Computing the Area of the Polygon:

Area can be calculated by multiplying the length and width of the polygon.

So, the area will be:

Therefore, the area of the polygon will be square units

Answer:

The number of non-congruent triangles that can be formed from the vertices of a cube are 3 triangles

Step-by-step explanation:

The number of non congruent triangles that can be formed by connecting 3 of thee vertices of the cube is found as follows;

The available different lengths of segments joining two vertices of a cube of side length s = 2 are;

2, 2·√2, and 2·√3

Therefore, since there are only three different side lengths we have the possible triangle dimensions given as follows

Distinct triangle one = 2, 2, 2·√2

Distinct triangle two = 2·√2, 2·√2, 2·√2

Distinct triangle three = 2, 2·√3, 2·√2

Therefore, there are ₃C₃ = 3 ways of forming three non-congruent triangles from the vertices of a cube.
