Question

Find the perimeter of the triangle.

Answer 1

13.83

Explanation:

`hf = \sqrt{({6 - 6 })^(2) +( {2 - 5)}^(2) }`

`= \sqrt{0 + {( - 3)}^(2) }`

`= √(0 + 9) = √(9) = 3`

`gf = \sqrt{ {(6 - 1)}^(2) + {(2 - 2)}^(2) }`

`= \sqrt{ {5}^(2) + {0}^(2) }`

`= \sqrt{ {5}^(2) } = 5`

`gh = \sqrt{ {(6 - 1)}^(2) + {(5 - 2)}^(2) }`

`= \sqrt{ {5}^(2) + {3}^(2) }`

`√(25 + 9)`

`= √(34) = 5.83`

perimeter = 3+5+5.83 = 13.83
