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

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

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
