3 0

Answer:

15.71

Step-by-step explanation:

Length AB =  sqrt ( (3-3)^2 + (2- - 1)^2) =  sqrt9 = 3

Length BC =  sqrt ( (-3-3)^2 + ( -1-2)^2) =  sqrt  45

Lemgth CA =  sqrt( 6^2) + (-1 - -1)^2 = sqrt 36 = 6

Perimeter = 3 + 6 + sqrt45

= 15.71

ss7ja [257]

Answer:

13

Step-by-step explanation:

This triangle appears to be 5 units wide and 12 units tall.

Using the pythagorean theorem, a^2 + b^2 = c^2, we get 25 + 144 = 169 or 13^2.

Therefore the answer is 13.
