Question

(06.04 MC) Find the perimeter of the image below:

Answer 1

Answer: 39 units

Step-by-step explanation:

Using the distance formula, we get that:

$PT=\sqrt{10^2 + 4^2}=\sqrt{116}\\\\TS=\sqrt{7^2 + 0^2}=7\\\\SR=\sqrt{7^2 + 1^2}=\sqrt{50}\\\\RQ=\sqrt{6^2 + 5^2}=\sqrt{61}\\\\PQ=\sqrt{2^2 + 6^2}=\sqrt{40}$

So, the perimeter is

$\sqrt{116}+7+\sqrt{50}+\sqrt{61}+\sqrt{40} \approx 39$
