As per the statement:
Adult red wolves vary in length from 137.16 cm to 168.64 cm.
To find the difference in length between the longest and shortest of these wolves.
Longest length of wolves = 168.64 cm
Shortest length of wolves= 137.16 cm
Then;
= 
Substitute the given values we have;
= 168.64 - 137.16 = 31.48 cm
therefore, the difference in length between the longest and shortest of these wolves is 31.48 cm
Multiply the values then either divide by 2 or multiply by 2
