    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
