Esther Harmon · Answer 1

60=2 (20) + 2x

x=10

Step-by-step explanation:

First, let's write some equations. I wrote 60=2 (20) + 2x, where x is the length of the room. To solve, first multiply 2 times 20 for 40 (60=40+2x). Then, I subtracted 40 from both sides (20=2x). Finally, I divided on both sides by 2 (10=x).
