The width of the rectangle is 10 cm, which is 14 cm less than its length. Find the perimeter of the rectangle.

1. The width of the rectangle is 10 cm. If it is 14 cm less than the length, then the length is correspondingly greater than the width by the same distance, that is, by 14 cm. We calculate the length of the rectangle:

10 + 14 = 24 (cm).

2. Find the perimeter of this rectangle. To do this, add twice the width and twice the length. We get:

2 x 10 + 2 x 24 = 20 + 48 = 68 (cm).

In decimetres, this value will be equal to 6.8 decimeters.

Answer: The perimeter of this rectangle is 68 centimeters or 6.8 decimeters.
