Well, there are 144 square inches in a square foot but you need two linear measurements ( x and y) before you can have square anything.
You can't get square inches from 151.25 or 77.5 inches only. If you had an area that measured 151.25 x 77.5 square, you WOULD have 11,721.88 square inches. Divide that by 144 and you get square feet, which WOULD be 81.40 ft^2. (length in inches x width in inches / 144 = sq.ft).
However, you can't get there with only one measurement.
