Question

the measure of one side of a square is (s+3) inches long. which pair of expressions both represent the perimeter of this square?

Answer 1

Answer:
perimeter = 4s + 12 inches
perimeter = 4(s+3) inches

Step-by-step explanation:
We are given that the side length of the square is s+3 inches
In a square, all sides are equal. This means that all four sides are s+3 inches
Now, to get the perimeter, we would add all four sides as follows:
perimeter = s+3+s+3+s+3+s+3 = 4s + 12 inches
For a square, since all sides are equal, we can simply get the perimeter by multiplying the side length by 4 as follows:
perimeter = 4(s+3) inches

Hope this helps :)
