    Pitagorin teorem :

    diagonal = sqrt ( a ^ 2 + a ^ 2 )

    diagonal = sqrt ( 2 * a ^ 2 )

    diagonal = a * sqrt ( 2 )


    13 = a * sqrt ( 2 ) Divide both sides by aqrt ( 2 )

    13 / sqrt ( 2 ) = a

    13 / 1.41421 = a

    9.19241131 = a

    a = 9.19241131 m

    1 m = 100 cm

    a = 9.19241131 m = 919.241131 cm

    a = 919 cm to the nearest centimeter?
