The formula that can be used to find the area of the figure shaded green is 9² - 4². The correct option is c 9² - 4²
Calculating area of a square
From the question, we are to determine the formula that could be used to find area of the figure shaded green
From the formula for calculating area of a square
A = s²
Where A is area
and s is the side length
Then, the area of the bigger square will be
A = 9²
NOTE: Side length of the bigger square is 9m
Then,
For the smaller square, which is not shaded green
A = 4²
NOTE: Side length of the smaller square is 4m
∴ Area of the figure shaded green = 9² - 4²
Hence, the formula that can be used to find the area of the figure shaded green is 9² - 4². The correct option is c 9² - 4²
