Question

The perimeter of the rectangle is 20CM. ONE SIDE IS 6 CM LONG.

Answer 1

Well, if one side is 6cm long, we know there is another side of equal length, or a parallel side. That's 12cm. Then all you have to do is 20 minus 16 (4), and divide by 2. Your answer is 2.

so, the final dimensions of the rectangle are: 6,6,4, and 4

Hope I helped :)

Answer 2

The other side is 4cm.
