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?

length of golden rectangle = 1.618

Step-by-step explanation:

It is given that the length (L) of golden rectangle is x

And width (W) of rectangle is x-1

so we have

L = x

W= x-1

Now we have area of rectangle given by

Area = L × W

Area = x(x-1)                             ( we plug L= x and W= x-1)

It is given that area of rectangle is 1 square unit.

So we have

      ( distribute x and remove parenthesis )

   ( subtract 1 from both sides )

Now to solve for x we need to use the quadratic formula

For quadratic equation

The quadratic formula is given by

Here we have a= 1 , b=-1 c=-1 , so we have

 or  

or x=-0.618

We can not have length negative

hence

length of golden rectangle = 1.618

the infinity sign

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
