Answer: 11.6 units.
Step-by-step explanation:
1. Plot the points as you can see in the graph attached.
2. As you can see, the lenght <em>TA</em> is 3 units.
3. Apply the formula for calculate the distance between two points, to calculate the length<em> TP</em> and <em>TA.</em> The formula is:

4. Therefore, you have:


5. The perimeter is the sum of the the lenght of each side, therefore:

6. To the nearest tenth unit:

<span>9x+8y=-3
5x-2y=-21
multiply 2nd equation by 4
</span><span>9x + 8y = -3
20x - 8y = -84
-----------------add
29x = -87
x = -3
</span><span>9x+8y=-3
</span><span>9(-3)+8y=-3
-27 + 8y = -3
8y = -3 +27
8y = 24
y = 3
answer
(-3,3)</span>
Answer:
