Math Problem Statement

A rectangular garden has a length that is 4 meters greater than its width. The perimeter of the garden is 36 meters. Determine the dimensions of the garden.

Solution

The problem states:

"A rectangular garden has a length that is 4 meters greater than its width. The perimeter of the garden is 36 meters. Determine the dimensions of the garden."

Solution:

  1. Let the width of the garden be ww meters.
  2. The length of the garden will then be w+4w + 4 meters.
  3. The formula for the perimeter of a rectangle is: Perimeter=2×(Length+Width)\text{Perimeter} = 2 \times (\text{Length} + \text{Width}) Substituting the given perimeter and dimensions: 36=2×(w+w+4)36 = 2 \times (w + w + 4)
  4. Simplify the equation: 36=2×(2w+4)36 = 2 \times (2w + 4) 36=4w+836 = 4w + 8
  5. Subtract 8 from both sides: 28=4w28 = 4w
  6. Divide by 4: w=7w = 7

Thus, the width of the garden is 7 meters, and the length is: w+4=7+4=11meters.w + 4 = 7 + 4 = 11 \, \text{meters}.

Final Answer:

  • Width: 7 meters
  • Length: 11 meters
