Answer:

Answer is A

Step-by-step explanation:

The golden rectangle is a rectangle whose sides are in the golden ratio, that is (a + b)÷a = a÷b, where a is the width and a + b is the length of the rectangle. The ratio calculator is an effective tool to assist in calculating ratios in general, while the golden ratio calculator will do the same as the golden rectangle calculator with the exception of finding the area of the rectangle.

Want to know how to use our golden rectangle calculator? Here are the steps:

Enter the width a.

Enter the length a + b or segment b

Find the area a ×(a + b)

If you know the area, divide by the missing part to get the other part.

Check your answer with the golden rectangle calculator.

An interesting aspect of the golden rectangle is that when the square section is removed, the remainder is another golden rectangle. Also, if you add another square to the rectangle with a side length of a+b, that is another golden rectangle. The golden rectangle calculator will verify this.
