Finding the Second Side of a Rectangle

To find the second side of a rectangle when the diagonal and one side are given, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the diagonal of the rectangle is given as 13 cm, and one of the sides is given as 12 cm. Let's denote the second side as x.

Using the Pythagorean theorem, we can set up the following equation:

x^2 + 12^2 = 13^2

Simplifying the equation, we get:

x^2 + 144 = 169

Subtracting 144 from both sides, we have:

x^2 = 25

Taking the square root of both sides, we find:

x = 5

Therefore, the second side of the rectangle is 5 cm.

Solution:

The second side of the rectangle is 5 cm.
