A "golden rectangle" is a rectangle where the ratio of the longer side to the shorter side is the "golden ratio." These rectangles are said to be visually pleasing. An example of a "golden rectangle" has a length equal to x units and a width equal to x – 1 units. Its area is 1 square unit. What is the length of this golden rectangle?
Answers
Answer:
Step-by-step explanation:
Approximately equal to a 1:1.61 ratio, the Golden Ratio can be illustrated using a Golden Rectangle. This is a rectangle where, if you cut off a square (side length equal to the shortest side of the rectangle), the rectangle that's left will have the same proportions as the original rectangle
The length of this golden rectangle is 1.618 units.
Given,
An example of a "golden rectangle" has,
length = x units,
width = (x - 1) units, and,
area = 1 unit².
To find,
Length of this golden rectangle.
Solution,
A golden rectangle is defined as a rectangle whose ratio of length to width is the "golden ratio".
Here it is given that, for the golden rectangle,
length = x units,
width = (x - 1) units,
area = 1 unit².
The area of this rectangle will be
It is given to be 1 unit². So,
Simplifying the above equation, we get,
Solving the above quadratic equation using the quadratic formula.
Here,
As length cannot be negative, so the only first value will be considered, that is,
units.
⇒ length of the rectangle = 1.618 units.
Therefore, the length of this golden rectangle is 1.618 units.
