The length of the rectangle is 20 cm and its area is 290 cm. What is the width of the rectangle? What is the perimeter of this rectangle?

1. According to the data presented in the problem statement, the length of the rectangle is 20 cm.

2. Since we also know that the area of this rectangle is 290 cm ^ 2, therefore we can calculate what the width of the given rectangle is. To do this, the area of the figure must be divided by the length of this rectangle. We get:

290/20 = 14.5 cm.

3. Now that we know both the length and the width of the rectangle, we can calculate what its perimeter is.

P = 2 * (20 + 14.5) = 2 * 34.5 = 69 cm.
