add all the numbers together
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
Length of prism * perimeter of triangular face.
It depends on the square yard you're talking about. If it is 1 yard by 1 yard, the perimeter will be 4 yard. If it is 1/2 yard by 2 yards, the perimeter will be 5 yards. If it is 1/4 yard by 4 yards, the perimeter will be 8.5 yards. In general, you will x yards by y yards with xy=1 and 2x+2y =p.
You look at the edge of the triangular prism and count the points
The perimeter of a triangle is the sum of the lengths of all its sides. In this case, since all sides of the triangular room are 4.5 meters long, the perimeter would be 4.5 + 4.5 + 4.5 = 13.5 meters. Therefore, the perimeter of the triangular room would be 13.5 meters.
Side1 + Side2 + Side3
The perimeter of one square yard is 4 yards. Since each side of the square yard is 1 yard long, adding the lengths of all four sides gives a total perimeter of 4 yards.

144 inches.
2*area of triangular base + perimeter of triangle*length of prism.

You need to find perimeter when you buy a house, because then you know where your yard begins and ends.
