Solution

The correct option is C Second sidewalk
Given, the first sidewalk is 15 yards long and the second sidewalk is 4 yards shorter than the first one.
So, the length of the second sidewalk = (15 − 4) = 11 yd
The third sidewalk is 3 yards longer than the first one.
So, the length of the third sidewalk = (15 + 3) = 18 yd
So, the length of the second sidewalk is less than 12 yards.
