The width of the rectangle is 6 cm, its perimeter is 32 cm. How long is it?

The perimeter is the sum of all four sides of the rectangle.
First, let’s calculate how many centimeters two equal sides of the width of a given figure occupy by adding these sides together:
1) 6 cm + 6 cm = 12 cm – occupy two sides of the width.
Next, we calculate how many centimeters are occupied by two identical sides of the length, if we subtract two sides of the width from the perimeter:
2) 32 cm – 12 cm = 20 cm – occupy two sides of the length.
Therefore, one side of the length of this figure is equal to:
3) 20 cm / 2 sides = 10 cm.
Total: 10 cm.
