Question

The perimeter of triangle formed by (4,3) (5,1) and (1,-5) is...​

Answer 1

Answer:

√52+√5+√73

Step-by-step explanation:

given that; points A(4,3):B( 5,1): C (1,-5)

AB = √[ (5-4)^2 + (1-3)^2 ]

AB. = √[1+4

AB. = √5

BC. = √[ (1-5)^2 + (-5-1)^2 ]

BC. = √ [16 +36

BC. = √52

AC. = √[ (1-4)^2 + (-5-3)^2]

AC. = √[9+64]

AC. = √73

perimeter of triangle ABC = AB + AC + BC
