Math Problem Statement

a gardener has 55 feet of fencing to be used to enclose a rectangular garden that had a border 2 feet wide surrounding it. If the length and width of the garden are to be the same what would be the dimensions of the garden

Solution

To solve this problem, we need to calculate the dimensions of the inner garden (the area within the fence, excluding the 2-foot border), given the constraint that the length and width are equal, and the total perimeter of the fencing is 55 feet.

Step-by-Step Solution:

  1. Let the side length of the garden be denoted by xx (since the length and width are the same).

  2. The border surrounding the garden is 2 feet wide, meaning the total dimensions including the border will be x+2+2=x+4x + 2 + 2 = x + 4 feet for both the length and width (since the border adds 2 feet on each side).

  3. The perimeter of the entire enclosed area (garden + border) is given by: P=2×(x+4)+2×(x+4)=2(2(x+4))=4(x+4)P = 2 \times (x + 4) + 2 \times (x + 4) = 2(2(x + 4)) = 4(x + 4)

  4. The gardener has 55 feet of fencing, so we set up the equation for the perimeter: 4(x+4)=554(x + 4) = 55

  5. Solve for xx: x+4=554=13.75x + 4 = \frac{55}{4} = 13.75 x=13.754=9.75x = 13.75 - 4 = 9.75

Thus, the side length of the garden is 9.75 feet.

Final Answer:

The dimensions of the garden are 9.75 feet by 9.75 feet.
