All you know about the plot of land below is what's written here, but even these few measurements offer you enough information to accurately calculate the plot's perimeter.
In feet, what is the length of the perimeter?
Be careful when considering your answer. The diagram may not be proportionally accurate.
You can find the lengths of the unlabeled sides by looking at the sides with known lengths.
Also, have you noticed that every corner of the plot is a right angle? This is key.
If you draw a line like the dotted yellow one shown above, you can see that the right side is five feet. Therefore, red lines X, Y, and Z must add up to a length of five feet.
Next, you have two horizontal segments to deal with, A, and B. Since A plus B equals three feet, and you have two sets of A and B, you have a total of six feet. Add everything up and you have a perimeter of 26 feet.
