Answer 2

Finding the Sides of a Rectangle

To find the sides of a rectangle, you can use the following methods:

Method 1: Using Perimeter - The perimeter of a rectangle can be calculated using the formula: P = 2 * (a + b), where 'a' and 'b' are the lengths of the sides of the rectangle. - The perimeter is the sum of all the sides of the rectangle. - Therefore, to find the sides of the rectangle, you can use the formula: P = a + b + c + d, where 'a', 'b', 'c', and 'd' are the sides of the rectangle.

Method 2: Using Area - The area of a rectangle can be calculated using the formula: A = length * width. - If the area and one side of the rectangle are known, the other side can be found by dividing the area by the known side length. - For example, if the area is 10 and one side is 5, the other side can be found by dividing the area by the known side length: A = 10, side length = 5. Therefore, the other side length = 10 / 5 = 2.

Method 3: Using Diagonals - The sides of a rectangle can also be found using the Pythagorean theorem if the length of the diagonal and one side of the rectangle are known. - The Pythagorean theorem states that in a right-angled 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 lengths of the other two sides. - Therefore, if the length of the diagonal and one side of the rectangle are known, the other side can be found using the Pythagorean theorem.

Method 4: Using Trigonometry - Trigonometric functions can also be used to find the sides of a rectangle if the angles and one side length are known. - By using trigonometric functions such as sine, cosine, or tangent, the lengths of the sides can be calculated based on the known angle and side length.

These methods provide different approaches to finding the sides of a rectangle based on the available information and the specific requirements of the problem.
