Answer:
225sqft with 1in -> 5ft  = 9sqin
147sqft with 1in -> 7ft = 3sqin
256sqft with 1in ->8ft = 4sqin
128sqft with 1in -> 4ft = 8sqin
Step-by-step explanation:
To change from feet to inches, you just divide by the scaling factor (5, 7, 8, or 4) in this problem. Â But because it is square feet to square inches, you must divide by the square of the scaling factor:
5*5 = 25
7*7 = 49
8*8 = 64
4*4 = 16
So:
225/25=9
147/49 = 3
256/64 = 4
128/16 = 8
