If you want a shorter way to find the perimeter then just multiply how many sides and the length of the side.
4 x4 = 16
However this only works if the 2D shape is an equilateral. So this trick only works in certain situations.

Step-by-step explanation:

<u>YELLOW TRIANGLE:</u>

<u>\sin(30)  =  \frac{x}{12}  \\ x = 12 \sin(30)  = 6</u>

<u>PURPLE TRIANGLE:</u>

Since one of the angle is 45°, x = BC = 6

To prove:

\tan(45)  =  \frac{bc}{x}  \\ bc = x \tan(45)  = 6 \tan(45)  = 6

<u>PINK TRIANGLE:</u>

<u>\tan(60)  =  \frac{bc}{y}  \\ y =  \frac{bc}{ \tan(60) }  \\  =  \frac{6}{ \tan(60) }  \\  = 2 \sqrt{3}</u>
