The width of the swimming pool: is 6 meters.

  • Let the length of the rectangle be L.
  • Let the width of the rectangle be W.

Given the following data:

  • Perimeter of rectangle = 30 meters

To find the width of the swimming pool:

Translating the word problem into an algebraic equation, we have;

[tex]W = L - 3[/tex]  .....equation 1

⇒ [tex]L = W + 3[/tex]  .....equation 2

Mathematically, the perimeter of a rectangle is given by the formula;

[tex]P = 2(L + W)[/tex]  .....equation 3

Substituting the given values into the formula, we have;

[tex]30 = 2(W + 3 + W)\\\\30 = 2(2W + 3)\\\\30 = 4W + 6\\\\4W = 30 - 6\\\\4W = 24\\\\W = \frac{24}{4}[/tex]

Width, W = 6 meters.

Therefore, the width of the swimming pool: is 6 meters.
