    Answer:

    The answer is

    \sqrt{53}  \:  \:  \: or \:  \:  \: 7.28 \:  \:  \:  \: units

    Step-by-step explanation:

    The distance between two points can be found by using the formula

    d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

    where

    (x1 , y1) and (x2 , y2) are the points

    From the question the points are

    T(2,-2) , W(4,5)

    The distance between them is

     |TW|  =  \sqrt{ ({2 - 4})^{2}  +  ({ - 2 - 5})^{2} }  \\  =  \sqrt{( { - 2})^{2} + ( { - 7})^{2}  }  \\  =  \sqrt{4 + 49}  \\  =  \sqrt{53}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 7.2801...

    We have the final answer as

     \sqrt{53}  \:  \:  \: or \:  \:  \: 7.28 \:  \:  \:  \: units

    Hope this helps you
