**Area of a Rectangle - Change in Length and Its Affect on Area**

This problem involves determining how a change in length affects the area of a rectangle. Take note that when you change the length, the width will be affected too.

Example:

A string is formed into a rectangle with an area of 12 cm^{2}. If it is reshaped so that the 6 cm side is 2 cm shorter, how will the area change?

**Area of Rectangles - Algebra Word Problems**

Example:

The length of rectangle is 5 units more than twice its width. If the area is 250 sq. units the find the dimensions of the rectangle.
**Writing quadratic equations to solve word problems: Area of a rectangle**

Example:

The length of a rectangular field is 3 m more than the width. The area is 108 m^{2}. Find the dimensions of the field.
