The side of the rectangle is 15 cm and its diagonal is 17 cm, you will find the area of the rectangle.

Let x denote the length of the second side of this rectangular quadrangle.

The statement of the condition for this task states that the length of the first side of this

In the formulation of the condition for this task, it is reported that it is 15 cm, and its diagonal is 17 cm, therefore, using the Pythagorean theorem, we can compose the following equation:

15 ^ 2 + x ^ 2 = 17 ^ 2,

solving which, we get:

x ^ 2 = 17 ^ 2 – 15 ^ 2;

x ^ 2 = (17 – 15) * (17 + 15);

x ^ 2 = 2 * 32;

x ^ 2 = 64;

x = √64 = 8 cm.

Knowing the lengths of the sides, we find the area of the rectangle:

15 * 8 = 120 cm ^ 2.

Answer: 120 cm ^ 2.
