  1. each side of the new area of the garden = 13
    since 13x13 = 169
    (side x side = area of square)
    so 13-9
    =4m
    Therefore, 4m should be the answer

  2. ( x + 9 ) ^ 2 = 169 Take the square root of both sides

    x + 9 = 13 Subtract 9 from both sides

    x + 9 - 9 = 13 - 9

    x = 4

    The length of the original garden = 4 m
