To solve this problem, we need to first find the dimensions of the side of the blue and purple squares.

We're given that the purple (smaller) square has a side length of x inches.
We are also given that the blue band has a width of 5 inches.
Since the blue band surrounds the purple square on both sides, the length of the blue square is x+2(5)=x+10 inches.

The net area of the band is therefore the difference of the area of the blue square and the purple square, namely take out the area of the purple square from the blue.

Therefore
Area of band
=(x+10)^2-x^2    [recall (a+b)^2=a^2+2ab+b^2
=x^2+20x+100-x^2
=20x+100   or 20(x+5)  if you wish.

e-lub [12.9K]

Answer:

<u>25%</u> is the percent error.

Step-by-step explanation:

Given:

The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

Now, to find the percent error.

As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.

<em>The actual measure</em> = 2 million.

The estimated measure = 2.5 million.

<em>So, the error</em> = 2.5-2=0.5\ million.

Now, to get the percent error:

\frac{0.5}{2} \times 100.

=0.25\times 100

=25\%.

Therefore, 25% is the percent error.
