Answer:
aw ty but is there a question?
Step-by-step explanation:
Find the total length in inches of one of the rolls:
15*12=180 inches.
Now multiply the length of one roll (180 inches) by 2 to find the total length:
180*2=360 inches.
Divide by the width of the strips to find the total number of strips:
360/9=40 strips
