The area of the blue rectangle is 8/11 of the flag
<h3>Area</h3>The area of a shape is the amount of space it occupies
The width is given as:
<h3>Blue region </h3>
The blue region of the American flag has a dimension of 8 by 11 stars.
So, we have:
Where x represents the length of the blue region.
Express the ratio as fractions
Multiply both sides by 2/5
Rewrite as:
The area is then calculated as:
Simplify
Hence, the area of the blue rectangle is 8/11 of the flag

There are 120 ways in which 5 riders and 5 horses can be arranged.
We have,
5 riders and 5 horses,
Now,
We know that,
Now,
Using the arrangement formula of Permutation,
i.e.
The total number of ways ,
So,
For n = 5,
And,
r = 5
As we have,
n = r,
So,
Now,
Using the above-mentioned formula of arrangement,
i.e.
The total number of ways ,
Now,
Substituting values,
We get,
We get,
The total number of ways of arrangement = 5! = 5 × 4 × 3 × 2 × 1 = 120,
So,
There are 120 ways to arrange horses for riders.
Hence we can say that there are 120 ways in which 5 riders and 5 horses can be arranged.
