Question 758150
using the formula: square root of (x2 - x1)^2 + (y2 - y1)^2
AB    (0-(-3))^2 + (4 - 0)^2
         = 9 + 16
         = 25
Square root = 5
BC    (3 - 0)^2 + (0 - 4)6"
         = 9 + 16
         = 25
Square root = 5
AC     (3 - (-3)^2 + (0 - 0)^2
           81
Square root = 9

Size of AB - 5
Size of BC - 5
Size of AC - 9
Perimeter = 23 units
Hope this helps
:-)
