The area of the rectangle is 14cm2, and the length is 7cm. Find the width and perimeter of the rectangle.?

Let’s denote by c the width of the given 4-gon, all four angles of which are 90 degrees.

In the initial data for this task, it is reported that the length of this quadrangle is 7 cm, and the area of this geometric figure is 14 cm², therefore, we can draw up the following equation:

7 * c = 14,

solving which, we get:

7 * s / 7 = 14/7;

c = 2 cm.

Knowing the length and width, we find the sum of the lengths of all four sides of this quadrangle:

7 + 2 + 7 + 2 = 9 + 9 = 18 cm.

Answer: the width is 2 centimeters, the perimeter is 18 centimeters.
