Describe a real-world scenario and which it would be important to apply trigonometric ratios or special right triangles.

Most notable application scenario is civil engineering. Trigonometric calculations are essential when projecting buildings, bridges, parking lots, or pretty much anything that is supposed to be used as a piece of infrastructure. Failure to calculate properly can be disastrous and can even cost people lives if bridges fall or roofs on buildings crash or similar.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
