    ( n + 4 )² - ( n + 1 )( n + 2 ) = 29

    5n + 15 = 29

    n = 3

    Area of EFGH

    = ( n + 1 )( n + 2 )

    = ( 3 + 1 )( 3 + 2 )

    = 20 cm²

    Shaded region: (n+4)(n+4) - (n+1)(n+2) = 29

    Solution to the equation: n = 3

    Shaded region: 49 - 20 = 29

    Clear region rectangle EFGH = 20 square cm
