Answer 1

You wrote: The lenght of a room is 10 feet less then triple its width. The perimeter of the room is 100 feet.

 

Corrected: The length of a room is 10 feet less than triple its width. The perimeter of the room is 100 feet.

 

Here's a QUESTION based on this given information:  Find the width of the room.

P = 100 = 2(L+W)

50 = L + W

L = 3W-10

Substituting, 50 = 3W - 10 + W.  YOU can finish the job, solving for W.
