PLEAS HELP! Find the perimeter of this shape. Triangle with the given vertices: C(3, 4), A(5, -4) and T(2, 2).
​

17.19 units.

Step-by-step explanation:

First calculate the distance between the 3 points to get the lengths of sides of the triangle.

Side AC = sqrt( (3-5)^2 + (4- -4)^2) = sqrt68

Side AT = sqrt((5-2)^2 + (-4-2)^2 = sqrt45

Side CT = sqrt((3-2)^2 + (4-2)^2) = sqrt5

So the perimeter = sqrt68 + sqrt45 + sqrt5

= 17.19 units.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
