Answer:

Scientific models are representations of objects, systems or events and are used as tools for understanding the natural world. Models use familiar objects to represent unfamiliar things. Models can help you visualize, or picture in your mind, something that is difficult to see or understand.

Jamie needs to build a fence around his garden, as illustrated by polygon ABCDEF on the coordinate grid below. If each unit repr

quester [9]

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:

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

The perimeter of the fence is the sum of all the sides of the polygon = 5 + 5 + 5 + 3 + 5 + 3 = 26 yards
