To calculate the area of a shape formed by grey squares, we first need to determine the total number of squares that make up the shape. Since each grey square measures 1cm in width and 1cm in length, the area of one square is:
Area of one square = width × length = 1cm × 1cm = 1 cm²Next, to find the total area of the entire shape, we simply multiply the area of one square by the total count of the grey squares present in the shape. For example:
- If there are 5 squares, then Total Area = 5 squares × 1 cm²/square = 5 cm².
- If there are 10 squares, then Total Area = 10 squares × 1 cm²/square = 10 cm².
- And so on…
In summary, the formula to find the area is:
Total Area = Number of Squares × Area of One SquareBy simply counting the grey squares, you can quickly calculate the total area of the shape!
