The answer to 4 feet 2 inches times 3 feet 4 inches? (4' 2" x 3' 4") is displayed below:
  
13.8888888888889 square feet
  
 
Here is how we calculated 4 feet 2 inches times 3 feet 4 inches to get the answer above:
  
First, we converted feet to inches so we are only dealing with inches.
  
4 feet 2 inches = 50 inches 
3 feet 4 inches = 40 inches
  
Then, we multiplied 50 inches by 40 inches to get the total number of square inches:
  
50 x 40 = 2000 square inches.
  
Finally, we converted 2000 square inches into feet as follows.
  
2000/(12*12) = 13.8888888888889 square feet
  
Note: There are 12 inches in a foot. Thus, you multiply feet by 12 to get only inches.
Since we have both height and length in square inches, we divided by 12X12.
