Answer:
E. 57 feet
Step-by-step explanation:
If you draw a rectangle and label the long side 5+2x, and the short side x, then that represents the rectangular floor.
The 2x is "<em>twice the width</em>".
The 5 added to the 2x is "<em>5 feet longer than</em>"
The x is the width of the room.
If the equation for the whole perimeter is 2(5+2x)+2x=166 <-(The perimeter)
(Both of the long sides)^ ^(Both of the short sides)
Then we need to solve for x.
Next, we input the value we got into the equation 5+2x (The length of one side) and solve
So the length of the room is 57 feet.
Hope this helps!
