Given a rectangle 9cm and 4cm. the length of each side was doubled and a rectangle was constructed

Given a rectangle 9cm and 4cm. the length of each side was doubled and a rectangle was constructed with new side lengths. Find the perimeter of the new rectangle.

Determine how many centimeters correspond to the perimeter of the original rectangle, knowing that by definition it is equal to the sum of its measurements multiplied by two:

2 * (9 + 4) = 26.

Let us determine how many centimeters the perimeter of the rectangle with enlarged sides corresponds to, knowing by the condition of the problem that each of the dimensions of the original rectangle was doubled:

26 * 2 = 52.

Answer: The perimeter of the enlarged rectangle is 52 centimeters.
