To find the area of the yellow square, we first need to identify the relationship between the areas of the squares provided.
We know:
- The area of the green square is 9 ft².
- The area of the red square is 16 ft².
If we assume that the yellow square's area is the sum of the areas of the green and red squares, we can proceed as follows:
Area of the yellow square = Area of the green square + Area of the red square
Area of the yellow square = 9 ft² + 16 ft² = 25 ft².
Therefore, the area of the yellow square is 25 ft².
The correct response is: A 25 ft².
