| In order to find the area of a rectangle, we must calculate the product of the lengths of its two adjacent sides. Thus, to find the length of one side we have to find the quotient of the area and the second side. S = a * b, where a is the length and b is the width. Let’s calculate what the length of the second side is, knowing that the area is 1.2 m², and the other side is 0.8 m.

b = 1.2 / 0.8 = 1.5 m.

Let’s calculate what the sum of two adjacent sides of the rectangle is equal to.

0.8 + 1.5 = 2.3 m.

Answer: 2.3 m.
