Answer: The lenght of the missing side is 4 cm

Step-by-step explanation:

The correct question is:

The perimeter of the rectangle is 20cm. One side is 6cm. What is the length of the missing side?

So, to answer it we have to apply the next formula:

Perimeter of a rectangle = 2 width + 2 length

Replacing with the values given: (assuming that the side given is the length of the rectangle)

20 = 2 (6) + 2x

Solving for x:

20 = 12 + 2x

20-12 = 2x

8 = 2x

8/2 = x

4=x

The length of the missing side is 4 cm
