Answer: The lenght of the missing side is 4 cm
Step-by-step explanation:
The correct question is:
<em>The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?</em>

Replacing with the values given: (assuming that the side given is the length of the rectangle)
20 = 2(6) + 2x

8/2 =x
4=x
The length of the missing side is 4 cm
