Respuesta :
The perimeter of a triangle with vertices located at (1,4), (2,7), and (0,5) is 7.40 units
What is perimeter?
Perimeter is the sum of the whole sides of a triangle. Therefore, let's find the distance of each sides using distance formula as follows;
(1, 4)(2, 7)
d = √(7 - 4)²+(2 - 1)² = √3² + 1² = √10
(1, 4)(0, 5)
d = √(5- 4)² + (0 - 1)² = √2
(2, 7)(0, 5)
d = √(5 - 7)²+(0 - 2)² = √4+4 = √8
Therefore,
perimeter = √10 + √2 + √8 = 7.37421356237 = 7.40 units
