Given parameters:

Dimension of the flowerbed  = 4ft by 7ft

Unknown:

Number of feet to build the flowerbed = ?

Since the flowerbed will be surrounding the flows, we should simply find the perimeter of the bed.

 This is a rectangular area;

  Perimeter = 2(L + B)

Input the parameters and solve;

   Perimeter  = 2 (4 + 7)

    Perimeter = 2 x 11 = 22cm

The perimeter of the board is 22cm
