If you guys think there is any mistake in the answers , please let me know.

To calculate the area and perimeter of triangles, we need more information than just the given values. The answers you provided (11.55m, 181.12mm, 21in, 22ft, 13mm) appear to be the results of some calculations, but without the corresponding question or triangle measurements, I cannot provide you with the step-by-step process. Please provide the specific questions or additional information, and I'll be happy to help you with the calculations.

To find the area and perimeter of triangles, you need the measurements of the triangle's sides. However, in this case, you have only provided the answers without any accompanying information or question. In order to explain how to find the area and perimeter, I will need more details about the triangles and their measurements.
