Question 445091: the length of a rectangle is one inch more than twice the width. The perimeter is 110 inches. Find the length and the width of the rectangle Answer by chriswen(106) (Show Source):
You can put this solution on YOUR website! Let x in be the width.
Let 2x+1 in be the width.
...
P=2(l+w)
110=2(2x+1+x)
110=2(3x+1)
110/2=3x+1
55=3x+1
3x=55-1
3x=54
x=54/3
x=18
2x+1=37
...
Therefore, the length of the rectangle is 37 in and the width is 18 in.
