mariarad [96]

Answer:

8 $\sqrt{13}$ units

Step-by-step explanation:

We know that:

P = 4a

We can find one side by distance formula:

a = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
a = $\sqrt{(10 - 4)^2+(-5+9)^2} = \sqrt{36+16} = \sqrt{52} = 2\sqrt{13}$

Then the perimeter is:

P = 4*2 $\sqrt{13}$ = 8 $\sqrt{13}$ units
