The length of the rectangle is 11 cm. Estimate how many centimeters its width should be so that the perimeter of this rectangle is less than the perimeter of a square with a side of 8 cm.

To solve the problem, first calculate the perimeter of the square, knowing that the side of the square is 8 cm P = 8 * 4 = 32 cm
From the problem statement, we know that the two sides of the rectangle are 11 cm long each, together 11 * 2 = 22 cm
The perimeter of the square is 32 cm Half of the perimeter of the rectangle is 22 cm so that their perimeters are equal
on both sides of the width of the rectangle must be 32-22 = 10 cm, That is, 5 cm each. Therefore, in order for the perimeter of this rectangle to be less than the perimeter of this square, the width of its sides must be less than 5.
Answer: <5 cm.
