Question

One side of a square is 3x + 2. Which expression represents the perimeter?

Answer 1

Your answer would be 12x + 8 because there are 4 sides to a square and they are all 3x + 2, so you would need to multiply 3x + 2 by 4 which you can do by expanding brackets which gives you 4(3x + 2) and thus when you multiply it out you get 12x + 8. I hope this helps!

Answer 2

Hi!

When finding the perimeter of a square, you multiply the value by 4.

4(3x + 2)
12x + 8

The answer is 12x + 8

Hope this helps! :)
