Jim is making a comforter for his king-sized bed. He needs two pieces of fabric that are 2 feet longer and 2 feet wider than the bed, which measures 6 feet long by 8 feet wide. How many square feet of fabric does Jim need to buy?
First find the length of each piece of fabric by adding 2 feet to the bed's length: 6 feet + 2 feet = 
<gadget id="calculator">6+2</gadget>
<output>8</output>
8 feet.
Then find the width of each piece of fabric by adding 2 feet to the bed's width: 8 feet + 2 feet = 
<gadget id="calculator">8+2</gadget>
<output>10</output>
10 feet.
Then find the square footage of each piece of fabric by multiplying its length and width: 8 feet * 10 feet = 
<gadget id="calculator">8*10</gadget>
<output>80</output>
80 square feet.
Then double that amount since Jim needs two pieces of fabric: 80 square feet/piece * 2 pieces = 
<gadget id="calculator">80*2</gadget>
<output>160</output>
160 square feet.
