An artist is using tiles and boards for a project. A tile has length 1/4 ft and width 1/4 ft. A board has length 1/4 yd and width 1/4 yd. What is the ratio of the length of the tile to the length of the board? What is the ratio of the area of the tile to the area of the board?

Answers

Answer:

Ratio of lengths is 1:3

Ratio of areas is 1:9

Step-by-step explanation:

Firstly, we need the units to be same

Mathematically, 1 yard = 3 feet

A length of 1/4 yards = 1/4 * 3 = 3/4 feet

A width of 1/4 yards = 1/4 * 3 = 3/4 feet

The ratio of the length of the tile to the length of the board

that would be;

1/4 : 3/4 = 1: 3

Let’s now work with area

Mathematically, area in both cases is length * width

For the board, we have that;

3/4 * 3/4 = 9/16 square feet

For the tile, we have that;

1/4 * 1/4 = 1/16 square feet

so the ratio of the tile area to the board area will be;

1/16 : 9/16 = 1: 9

Describe the work of art. Make detailed notes about what you see in the artwork. Notice what type of medium was used to make the piece. This is where you would look at the elements of art (Line, Color, Shape, Texture, Value, Space, and Form) and how they are used. 2. Analyze the work of art. This is where you look at how the piece is put together. This is where you look at how the artist used the principles of design (Balance, Proportion, Harmony, Contrast, Emphasis, Movement, Pattern, Rhythm, Variety, and Unity) in the piece of art. 3. Interpret the work of art. This is where you assign meaning to the artwork. Sometimes it is helpful to know more about the artists life when working on this portion of a critique. It may help you to understand what the artist intended you to feel. What do you think was the artists goal with this work? Whether you have that information or not, you still can get a sense of what the artwork is telling you. 4. Judge the artwork. At this point you decide if the work is successful or not. In order to do this you must decide if the artist achieved the goal that you think they had in creating the art.
