The rectangle has a perimeter of 14 cm. What is the longest length this rectangle can have.

Let’s find how many centimeters are the sum of the length and width of the rectangle.

14/2 = 7 cm.

In this case, for integer values, the maximum length of the figure is 6 cm.

Then the width will be equal to:

7 – 6 = 1 cm.

The smallest value for the length of the rectangle is 4 cm.

Then the width will be:

7 – 4 = 3 cm.

If the length of the rectangle is 3.5 cm, then it will be a square in which all sides are equal.

14/4 = 3.5 cm.

Answer: The largest integer length is 6 cm, the smallest is 4 centimeters.
