The length of the rectangle is 9m. What is its width if the perimeter of this rectangle is 26m?

The length of the rectangle is 9 m.

The perimeter of the rectangle is 26 m.

Determine the width of the rectangle. We write down the resulting solution.

The perimeter is the sum of the lengths of all sides. Let’s write down the formula.

P = 2 * (a + b).

Determine the width of the rectangle.

c = (P – 2a) / 2.

c = (26 – 2 * 9) / 2 = (26 – 18) / 2 = 8/2 = 4.

Therefore, the width of this rectangle is 4 centimeters.

Answer: the width is 4 cm.
