Final answer:
To find the total length of 14 exercise mats, multiply the length of one mat by the number of mats: 122 cm × 14 = 1708 cm.
Step-by-step explanation:
To find the total length of 14 exercise mats, we need to multiply the length of one mat by the number of mats. Each exercise mat is 122 centimeters long, so we can multiply 122 by 14 to get the total length.
122 cm × 14 = 1708 cm
Therefore, the total length of 14 exercise mats is 1708 centimeters.
