Question 857588: A rectangular room is twice as long as it is wide, and its perimeter is 54 meters. Find the length of the room. Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! L = 2W
2W + 2L = 54
Substitute the value of L from the first equation into the second.
2W + 2(2w) = 54
2W + 4W = 54
6W = 54
W = 9
If W is 9, then L = 2*9, or 18
.
Add the L and W to check the perimeter.
9 + 9 + 18 + 18 =
18 + 36 =
54
success!
