| 1. In order to find the area of a rectangle, you need to multiply one of its sides by the other. So, in order to find the unknown side of a rectangle, you need to divide its area by the length of the known side. Let’s calculate the second side of the rectangle if we know that its area is 7.82 cm ^ 2, and the length of the known side is 4.6 cm.

7.82 / 4.6 = 1.7 cm.

2. Find out the perimeter of this rectangle. In order to find the perimeter of a rectangle, you need to calculate the sum of the lengths of all its sides.

4.6 + 4.6 + 1.7 + 1.7 = 12.6 cm.

Answer: The perimeter of the rectangle is 12.6 cm.
