Answer:

A=10 square units

Step-by-step explanation:

The area of a shape is the amount of space it can occupy.

The area of the polygon is [tex]8+ \sqrt 2[/tex] square units

Given

[tex]A=(0,5)[/tex]

[tex]B =(2,5)[/tex]

[tex]C =(2,3)[/tex]

[tex]D = (3,2)[/tex]

[tex]E = (1,2)[/tex]

[tex]F = (0,3)[/tex]

[tex]G = (-4,3)[/tex]

First, we plot the points (see attachment)

From the attached image, the polygon can be into split to several shapes as follows:

  • Square ABCF
  • Triangle AFG
  • Rhombus CDEF

Given

[tex]A=(0,5)[/tex]

[tex]B =(2,5)[/tex]

[tex]C =(2,3)[/tex]

[tex]D = (3,2)[/tex]

[tex]E = (1,2)[/tex]

[tex]F = (0,3)[/tex]

[tex]G = (-4,3)[/tex]

First, we plot the points (see attachment)

From the attached image, the polygon can be into split to several shapes as follows:

  • Square ABCF
  • Triangle AFG
  • Rhombus CDEF

The area of the square is:

[tex]Area = Length^2[/tex]

using the following distance formula

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

So, we have:

[tex]A\ F = \sqrt{(0- 0)^2 + (5- 3)^2}[/tex]

[tex]A\ F = \sqrt{4}[/tex]

[tex]A\ F = 2[/tex]

So, we have:

[tex]Area =2^2[/tex]

[tex]Area = 4[/tex]

The area of the triangle is:

[tex]Area= 0.5 \times Base \times Height[/tex]

Where

[tex]Height = A\ F =2[/tex]

[tex]Base =FG[/tex]

Side length FG is calculated as follows:

[tex]FG = \sqrt{(0 --4)^2 + (3 -3)^2}[/tex]

[tex]FG = \sqrt{16}[/tex]

[tex]FG =4[/tex]

So, we have:

[tex]Area= 0.5 \times Base \times Height[/tex]

[tex]Area = 0.5 \times 2 \times 4[/tex]

[tex]Area =4[/tex]

The area of the rhombus is:

[tex]Area= \frac{1}{2} (FD \times CE)[/tex]

Where:

[tex]FD = \sqrt{(1 - 3)^2 + (2 - 2)^2}[/tex]

[tex]FD = \sqrt{4}[/tex]

[tex]FD = 2[/tex]

[tex]CE = \sqrt{(2 -1)^2 + (3 -2)^2}[/tex]

[tex]CE = \sqrt{2}[/tex]

So, we have:

[tex]Area= \frac{1}{2} (FD \times CE)[/tex]

[tex]Area = \frac 12(2 \times \sqrt 2)[/tex]

[tex]Area = \sqrt 2[/tex]

So, the area of the shape is the sum of the three areas;

[tex]Area = 4 + 4 + \sqrt 2[/tex]

[tex]Area = 8+ \sqrt 2[/tex]

Hence, the area of the polygon is [tex]8+ \sqrt 2[/tex] square units
