Question

A rectangle's length is 3 more than it width, if the perimeter is 26 inches, what is the width of the
rectangle.

Answer 1

Answer:

So the width is 3.25

Step-by-step

If the perimeter of a rectangle is 300 and the length is two times the  

width, what are the length and the width?

• Call the width of the rectangle x.  Then, if the length is three times  the width, the length must be 3x.  
• Now, if you have a rectangle whose  width is x and whose length is 3x, the perimeter must be  3x + 3x + x + x = 8x.  
• You are told that the perimeter is 26, so the equation is 8x = 26.  
• Dividing both sides by 8, one gets x = 3.25.  So the width is 3.25 and the  length is 6.5.
