Rectangle side is represented by (2,3) and (-6,4). Find the perimeter of rectangle.

Could someone please help~

  • Calculus -

    x1 = 2

    x2 = -6

    y1 = 3

    y2 = 4


    Length of first side :

    a = x1 - x2

    a = 2 - ( - 6 )

    a = 2 + 6 = 8


    Length of second side :

    b = | ( y1 - y2 ) |

    b = | 3 - 4 |

    b = | - 1 |

    b = 1


    P = 2 ( a + b )

    P = 2 ( 8 + 1 )

    P = 2 * 9 = 18


    Remark :

    | |

    mean absolute value

    Thank you for answering.

    Don't I have to find the magnitude then use square root of the answer and multiply by 2? If so, could you show it.
