Question

what percentage of the shape is blue? write your answer using a percent sign (%).

Explanation:

Step1: Count total squares

Assume the shape is a \(10\times10\) grid. Total squares \(= 10\times10=100\).

Step2: Count blue squares

Count the blue - colored squares. There are \(30\) blue squares.

Step3: Calculate percentage

Percentage of blue squares \(=\frac{\text{Number of blue squares}}{\text{Total number of squares}}\times100=\frac{30}{100}\times100 = 30\%\)

Answer:

30%
