Break down this math problem: Tom has 4 bedrooms in his house.  They measure 20 by 12 feet each.  The living room is 5 times bigger than one bedroom.  The rest of the house is 1000 square feet.  What is the total area, in square feet, of the house?
The bedrooms are each 20*12=240 square feet
So in total the bedrooms are 240*4=960 square feet
The living room is 240*5=1200 square feet
So in total the house is 1200+1000+960=3160 square feet
