Answer:

Explanation:

The complete question is shown below.

The length between two points ( $x_1,y_1$ ) and ( $x_2,y_2$ ) is:

$Length=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

From the image attached we can get the polygon points as:

A(-5, 5), B(0. 5), C(4,2), D(1, -2), E(-2, -2), F(-5, 2). Hence the length of the polygon is gotten as:

$|AB|=\sqrt{(0-(-5))^2+(5-5)^2}=5\ yards \\\\|BC|=\sqrt{(4-0)^2+(2-5)^2}=5\ yards \\\\|CD|=\sqrt{(1-4)^2+(-2-2)^2}=5\ yards \\\\|DE|=\sqrt{(-2-1)^2+(-2-(-2))^2}=3\ yards\\ \\|EF|=\sqrt{(-5-(-2))^2+(2-(-2))^2}=5\ yards \\\\|FA|=\sqrt{(-5-(-5))^2+(2-5)^2}=3\ yards$
