Answer: 126 inches.
Explanation:
Step 1. Ok since there are 36 inches in 1 yard we need to multiply 36 by 3 to find how many inches there are in 3 yards.
36*3=108.
Step 2. Now we need to find out how many inched is in 0.5 yards. To do this we would divide 36 by 2.
36/2=18.
Step 3. Now all we have to do is add 108 to 18.
108+18= 126.
