Solution

The correct option is A Red ribbon
Let's calculate the length of each ribbon in centimeters.

The conversion table is represented as:

Length of red ribbon = 7 m 12 cm
= (7 × 100) cm + 12 cm
= 700 cm + 12 cm
= 712 cm

Length of blue ribbon = 65 dm 10 cm
= (65 × 10) cm + 10 cm
= 650 cm + 10 cm
= 660 cm

Length of yellow ribbon = 70 dm 7 cm
= (70 × 10) cm + 7 cm
= 700 cm + 7 cm
= 707 cm

Hence, the red ribbon is the longest.
