The area of the rectangle is 5.76 m2, and one of its sides is 3.6 m. Calculate the perimeter of the rectangle.

Find the length of the second side of this rectangle.

Let us denote it by x.

According to the condition of the problem, the length of one side of this rectangle is 3.6 m, and the area of ​​this rectangle is 5.76 m², therefore, we can make the following equation:

3.6 * x = 5.76.

We solve the resulting equation and find the length of the second side of this rectangle:

x = 5.76 / 3.6;

x = 1.6 m.

Knowing the lengths of the two sides of a given rectangle, we find its perimeter P as the doubled sum of the length and width of this rectangle:

P = 2 * (3.6 + 1.6) = 2 * 5.2 = 10.4 m.

Answer: the perimeter of this rectangle is 10.4 m.
