Question

find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x

16x + 8
10x + 4
12x + 4
8x + 2

Answer 1

Answer:

12x+4

Step-by-step explanation:

To find the perimeter of any shape you just have to take the sum of all the sides.

In this case you would write:

 4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)

Now you just have to simplify the expression which would give you:

12x+4 (after collecting like terms)

So the final answer will be 12x+4

Answer 2

4x+2+2x=6x+2 which is the same as 12x+4
