The answer to 5 feet 7 inches times 3 feet 9 inches? (5' 7" x 3' 9") is displayed below:
20.9375 square feet
Here is how we calculated 5 feet 7 inches times 3 feet 9 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
5 feet 7 inches = 67 inches
3 feet 9 inches = 45 inches
Then, we multiplied 67 inches by 45 inches to get the total number of square inches:
67 x 45 = 3015 square inches.
Finally, we converted 3015 square inches into feet as follows.
3015/(12*12) = 20.9375 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.
