Answer:
4x + 12
Step-by-step explanation:
The perimeter of a rectangle can be calculated as two times the length plus two times the width. So, the perimeter is:
Perimeter = 2(x + 2) + 2(x + 4)
Applying distributive property, we get:
Perimeter = 2*x + 2*2 + 2*x + 2*4
Perimeter = 2x + 4 + 2x + 8
perimeter = 4x + 12
Therefore, the perimeter is 4x + 12
