The length of a rectangular room is 5 feet longer that twice the width. If the rooms perimeter is 160 feet, what is the length of the room?

L = 2W + 5

 

Perimeter =  2 (L + W)

 

So

 

160  =  2  [ 2W + 5 + W]       divide  both sides by 2  and simplify

 

80  =  3W  + 5      subtract 5 from both sides

 

75  = 3W     divide both sides by 3

 

25  = W

 

L  = 2W + 5   =  2(25) + 5  =    55
