It’s number 1 the question is what is the greatest number of rows that their rectangles could have had

Question writers have to find different ways of asking the same question. Here we're being asked the Greatest Common Factor of 20, 28, and 44. Let's calculate that; then we'll talk about why.

4

Because 4 is a factor of 20, 28 and 44 it makes a rectangle with each of them: 4 by 5, 4 by 7, 4 by 11. Because 4 is the greatest common factor, that's the greatest number of rows that can be a common factor, which is what the question asks.

900 degrees

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
