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

It is known from the condition that the area of the rectangle is 5.76 m2, and one of its sides is 3.6 meters. In order to calculate the perimeter of a rectangle, first of all, let’s find the length of the second side.

Let’s remember the formula for finding the area of a rectangle.

S = a * b, where a and b are the length and width of the rectangle.

Substitute the known values and solve the equation.

3.6a = 5.76;

a = 5.76: 3.6;

a = 1.6 meters length of the second side.

We look for the perimeter by the formula:

P = 2 (a + b) = 2 (1.6 + 3.6) = 2 * 5.2 = 10.4 meters perimeter.
