Find the second side and perimeter of the rectangle. one side is 5 centimeters 2 millimeters and the area is exactly 65 cm2.

1. According to the data presented in the problem statement, the length of the first side of the rectangle is 5 cm 2 mm = 5.2 cm.

2. Let us calculate what the length of the second side of a given rectangle is equal to, if from the condition of the problem we also know that its area is 65 cm ^ 2. To do this, the area of the rectangle should be divided by the length of its known side, we get:

65 / 5.2 = 12.5 cm.

3. Now let’s find out what the perimeter of this rectangle is. To do this, you need to find the sum of the lengths of all its sides, we get:

P = (5.2 + 12.5) * 2 = 17.7 * 2 = 35.4 cm.
