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. 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
