Question 105769
The length of a rectangle is 5 in. more than twice its width.  If the perimeter of the rectangle is 40 in., find the width of the rectangle.
A)	4 in.
B)	5 in.
C)	6 in.
D)	7 in.

Let x = width of the rectangle
then 2x + 5 = length of the rectangle

We all know that the formula for the perimeter of a rectangle is {{{2L + 2W}}} or {{{2(L+W)}}}
So, it is stated in the problem that the perimeter is 40. Substituting:
{{{2(2x+5)+2(x)=40}}}
{{{4x+10+2x=40}}}
{{{6x=30}}}
{{{x=5}}}

B. 5 in

THank you.
