A square garden is surrounded by a walkway of width X. If the area of the garden is 484 ft2 and the area covered by both the gar
slavikrds [6]

The width of the walkway is 3 feet, If the area of the garden is 484 feet^{2} and the area covered by both the garden and the walkway (the entire square) is 784 feet^{2}.

Step-by-step explanation:

The given is,

                 Area of the garden is 484 feet^{2}

                 Area covered by both the garden and the walkway (the entire square) is 784 feet^{2}.

                Let, x - Width of the walkway

Step:1

                Formula to calculate area of square is,

                                A= a^{2}...........................(1)

                Where, r - Radius of square

Step:2

               For garden,

               A = 484 feet^{2}

               Equation (1) becomes,

                            484=a^{2}

               Take square root on both sides,

                               a=\sqrt{484}

                                a = 22 feet

               For garden and the walkway (the entire square),

               A = 784 feet^{2}

               Equation (1) becomes,

                            784=a^{2}

               Take square root on both sides,

                               a=\sqrt{784}

                                a = 28 feet

Step:3

                  Ref attachment,

                  Side of garden and the walkway =

                             Side of garden + 2 (width of the walkaway)....(1)

                                                 28 = 22 + 2 ( x )

                                             2 ( x ) =   28 - 22

                                                       = 6

                                                    x = \frac{6}{2}

                                        Width, x = 3 feet

Result:

          The width of the walkway is 3 feet, If the area of the garden is 484 feet^{2} and the area covered by both the garden and the walkway (the entire square) is 784 feet^{2}.
