Question

Find the perimeter of a triangle with vertices (2,4) (-1,3) and (2,-3).

Answer 1

14

Answer 2

(2,4) (-1,3) ---> √10

(-1,3) and (2,-3). ---> √45

(2,4) and (2,-3) ----> 7

perimeter = 7 + √45 +√10 =

7 + √10 + 3√5 ---> That's it --> these are not like terms. You can approximate the value of the radicals. but I don't know the instructions you had regarding that.


Note: √45 = √(3*3*5) = 3√5
