Answer:
5 rolls
Step-by-step explanation:
The perimeter lengths are the same because it's a square. So 12 times 4 is 48. You would need a minimum of 5 rolls because each roll as a length of paper of 10 feet. So 40 feet plus 8 would round to 50. That's why it would be 5 rolls.
3x -4 (5 - x) = 7x -20
3x-20+4x=7x-20
7x-20=7x-20
