Michelle's dad decides to put fencing around the backyard. He creates a scale drawing where every 3 inches represents 13 feet. No fence is needed against the house. Find the amount of fencing he needs for this project.

The amount of fencing he needs for this project is 247 feet.
Data;
To find the length of the fence required, we need to find the perimeter of the figure and note that this is excluding the perimeter of the house.
The perimeter of the figure is
[tex]P = 2(14+6) + 17 = 57in[/tex]
The perimeter of the figure is 57in.
But we were told that every 3 in represents 13 feet.
[tex]3in = 13ft\\57in = x\\x = \frac{57 * 13}{3} \\x = 247ft[/tex]
The amount of fencing he needs for this project is 247 feet.
