What percentage of the square's area is colored blue?

30% 35% 40% 45% 50%

Nice question, and I could see your diagram.

Several ways to do this, here is what I thought:

easy to get the equation of BD : y = -x + 4
and the equation of AQ = (1/2)x
so for the intersection:
(1/2)x = -x + 4
x = -2x + 8
3x=8
x = 8/3

so if we consider AB as the base and 8/3 as the height,
area = (1/2)(4)(8/3) = 16/3

I apologize, but as an AI text-based bot, I am unable to access external websites or view images. However, I can still guide you on how to determine the percentage of the square's area that is colored blue.

To find the percentage of the square's area that is colored blue, you need to compare the area of the blue section to the total area of the square. Here's how you can do it:

1. Obtain the dimensions of the square: Measure the length of one side of the square. Let's say it is "s" units.

2. Calculate the area of the square: The area of a square is given by the formula A = s^2, where "A" represents the area and "s" is the length of one side. Square the value of "s" to find the area.

3. Determine the area of the blue section: If you have access to the image, you can estimate or measure the dimensions of the blue section within the square. Calculate the area of the blue section using the appropriate geometric shape, such as a rectangle or triangle.

4. Calculate the percentage: Divide the area of the blue section by the total area of the square and then multiply by 100 to find the percentage. The formula is (Area of blue section / Total area of square) * 100.

With this information, you'll be able to figure out the percentage of the square's area that is colored blue.
