To compute the perimeter of a triangle given its vertices' coordinates, you first need to determine the lengths of each side using the distance formula. The distance formula between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
Assume the coordinates of the vertices of the triangle are \(A(x_1, y_1)\), \(B(x_2, y_2)\), and \(C(x_3, y_3)\). To find the perimeter \(P\) of the triangle, sum the lengths of all three sides:
\[ P = AB + BC + CA \]
Where:
- \(AB\) is the distance between points \(A\) and \(B\),
- \(BC\) is the distance between points \(B\) and \(C\), and
- \(CA\) is the distance between points \(C\) and \(A\).
Once you have computed the lengths of the sides, simply add them up and round your answer to the nearest tenth.
Please provide the coordinates of the triangle's vertices so that I can assist you in calculating the perimeter.
