A rectangle has the perimeter of 116 cm and its length is 1cm more than twice its width​

Find the dimensions of a rectangle given that its perimeter is 116

 cm and its length is 1

 cm more than twice its width.

Set up your solution using the variables L

 for the length, W

 for the width, and P

 for the perimeter. 

Part a: Using the definition of perimeter, what is an equation for P

 in terms of L

 and W

.

Part b: You also have to write an equation for L in terms of W

 in terms of W

.

Solve the equations from parts a and b.

Part c: The length is   cm.

Part d: The width is   cm.
