Well, isn't that a happy little question! When you multiply 90 by 63, you get 5,670. And since we're talking about feet here, we're just focusing on numbers, not actual physical feet. So, 5,670 is the answer to your mathematical question. Just remember, there are no mistakes, just happy little accidents in math!
90
63 sq feet
21 x 3 yards/foot = 63 feet
If that's 12 x 90 feet, it's 1080 square feet. If that's 12 x 90 inches, it's 7.5 square feet.
7/10 x 90 = 63
Multiply 90 x .63= 56.7 is 63% of 90
90 x 7 = 630 sq ft
3 x 30 = 90 square feet (90 ft2).
90
63 sq feet
1,449 square feet.
2,079
There are 63*3 = 189 feet in 63 yards, since there are 3 feet in a yard.
90 x 130 = 11,700 square feet.
There are: 90*49.5 = 4455 square feet
150 x 90 = 13,500 square feet
47' x 63' = 2,961 square feet.
