Question

A square has a length of 2(m+3). What is the perimeter of the square?

Answer 1

Answer:

8(m+3)

or 8m+24

Step-by-step explanation:

If one side x has a length of 2(m+3), then using the formula for the perimeter of a square P=4x

You get:

8(m+3)

or 8m+24

Answer 2

Answer:

8m + 24

Step-by-step explanation:

First, distribute the 2 so it will be easier to find the perimeter:

2(m + 3)

= 2m + 6

Since a square has 4 sides, we need to add this expression together 4 times:

(2m + 6) + (2m + 6) + (2m + 6) + (2m + 6)

Add like terms:

2m + 2m + 2m + 2m

= 8m

6 + 6 + 6 + 6

= 24

Add those together:

8m + 24 will be the perimeter
