A square has four equal sides.
So if a square has one side of length 3x+4, then the total perimeter is this multiplied by four.
The simplest way to do this is to just multiply each of the numbers in your side length by four, so the perimeter becomes 12x+16 (because 3x multiplied by 4 is 12x, and 4 multiplied by four is 16)
If you need to write this out in a mathematical way it would look like this:
Length of one side = 3x+4
Total perimeter = 4(3x+4)
4(3x+4) = 12x+16

With a square each and every side is equal to each of the other sides, so if one side is 3x+4 all the other sides are equal to 3x+4. Since it is a square you can just multiply by 4 to get the answer, which in this case is 12x+16.

The perimeter of a square is a side length times four. Thus the equation: p = 4s
Plugging in 3x + 4 in into s, you get:
p = 4(3x + 4)
p = 12x + 16

The perimeter is the distance around a shape. A square has 4 equal sides, so perimeter p is equal to:
p=4(3x+4)
p=12x+16

Squares have four equal sides. The perimeter is the sum of the length of those four side. If one side is (3x+4), four are 4(3x+4)=12x+16

perimeter of the square=4*one side
= 4(3x+4)
==12x+16. ANS.

Add together all the numbers with the common denominator. (I think that's the word I'm looking for.. I know my terms in French =P )
So a square has four sides, which would mean... :
3X+4+3X+4+3X+4+3X+4
=
(3X+3X+3X+3X)+(4+4+4+4)
=
12X+16
PS: You don't add all the "X"'s together, so the answer would be "3X "to the power of four"" but you just add the digits together..
Hope that helped. :)

The perimeter is round the outside so it must be 4(3x+4)

the only answer that can be assumed from the information given is 4(3x+4) because x was not given.. 4 times the equation because a square has 4 sides..

there are four sides in a square and they are all equal
so multiply the whole equation by 4
4(3x+4)
distribute
12x+16 is the answer
good luck
