Question

Help ASAP! you help me I can help you

Answer 1

Use the distance formula or Pythagorean Theorem to find the length of each of the sides.

(-5, -4) to (2, 6)

d = $\sqrt{(-5 - 2)^{2} + (-4 - 6)^{2} }$

  = $\sqrt{(- 7)^{2} + (-10)^{2} }$

  = $\sqrt{49 + 100}$

  =  $\sqrt{149}$

(2, 6) to (4, -4)

d = $\sqrt{(2 - 4)^{2} + (6 - (-4))^{2} }$

  = $\sqrt{(- 2)^{2} + (10)^{2} }$

  = $\sqrt{4 + 100}$

  =  $\sqrt{104}$

  = 2$\sqrt{26}$

(-5, -4) to (4, -4)

you can just count the distance between the coordinates: d = 9

Perimeter = (-5, -4) to (2, 6) + (2, 6) to (4, -4) + (-5, -4) to (4, -4)

                =       $\sqrt{149}$          +    2$\sqrt{26}$           +             9

Answer: $\sqrt{149}$ + $\sqrt{149}$  + 9
