The. correct. answer is c
Answer:
The answer is the last option: 12x - 6
Step-by-step explanation:
To find the perimeter of a rectangle we need to add the length of the four sides.
So, the sides of it are:
2 sides: 4x+ 3 an 2 sides: 2x
Then, our addition is 4x + 3 + 4x + 3 + 2x + 2x
Finally we simplify this adding like terms: 4x + 4x + 2x + 2x = 12x
3 + 3 = 6
The answer is: 12x + 6
6x9 + 3^2pi would be the area so 54+9pi=57.14
