1. The problem asks to measure the lengths of two rectangles to the nearest inch using the given ruler scales. 2. For rectangle (a), the ruler shows it starts at 0 and ends at 6 inches. So, the length is exactly 6 inches. 3. For rectangle (b), the ruler shows it starts at 0 and ends at 3 inches. So, the length is exactly 3 inches. 4. Therefore, the measurements to the nearest inch are: - Rectangle (a): 6 inches - Rectangle (b): 3 inches This is a straightforward measurement problem where the length is the difference between the end and start points on the ruler.
