The answer to 8 feet 9 inches times 3 feet 7 inches? (8' 9" x 3' 7") is displayed below:
31.3541666666667 square feet
Here is how we calculated 8 feet 9 inches times 3 feet 7 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
8 feet 9 inches = 105 inches
3 feet 7 inches = 43 inches
Then, we multiplied 105 inches by 43 inches to get the total number of square inches:
105 x 43 = 4515 square inches.
Finally, we converted 4515 square inches into feet as follows.
4515/(12*12) = 31.3541666666667 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.
