Answer 1

Answer:

The answer to your question is Perimeter = 26 units

Step-by-step explanation:

Data

Vertex

A(-2, 3)

B (4, 7)

C (7, -1)

Process

1.- Find the distance between the vertex

dAB = $\sqrt{(4 + 2)^{2} + (7-3)^{2}}$

dAB = $\sqrt{6^{2}+ 4^{2}}$

dAB = $\sqrt{36 + 16}$

dAB = $\sqrt{52}$

dBC = $\sqrt{(7-4)^{2} + (-1 -7)^{2}}$

dBC = $\sqrt{3^{2} + 8^{2}}$

dBC = $\sqrt{9 + 64}$

dBC = $\sqrt{73}$

dAC = $\sqrt{(7 + 2)^{2}+ (-1-3)^{2}}$

dAC = $\sqrt{9^{2} + 4^{2}}$

dAC = $\sqrt{81 + 16}$

dAC = $\sqrt{97}$

Perimeter = $\sqrt{52} + \sqrt{73} + \sqrt{97}$

Perimeter = 7.21 + 8.54 + 9.84

Perimeter = 25.59 ≈ 26 units
