A machine cuts a strip of carpet into two pieces. The length of the smaller piece is 5 meters greater than the length of the larger piece. If the length of the smaller piece is 12 meters, the length of the bigger piece is (?)
meters and the total length of the carpet is (?)
meters.

Answers

Answer:

7 meters and 19 meters

Step-by-step explanation:

12-5=7

12+7=19

Answer:

I think you mean "the length of the smaller piece is 5 meters shorter than the length of the greater piece."

If that's so, then the answer is that the larger piece is 17 meters, and the total length is 29 meters.

If you mean what you wrote, then the answer is that the larger piece is 7 meters and the total length is 19 meters.
