What percent is modeled by the grid?

Question

A grid model with 100 squares. 33 squares are shaded.
23%
30%
33%
40%

Answer 1

To find the percentage represented by the shaded squares in the grid model, you can use the following formula:

\[ \text{Percentage} = \left( \frac{\text{Number of shaded squares}}{\text{Total number of squares}} \right) \times 100 \]

In this case, there are 33 shaded squares out of a total of 100 squares:

\[ \text{Percentage} = \left( \frac{33}{100} \right) \times 100 = 33% \]

Therefore, the correct answer is 33%.
