148.5 square yards of floor covering will be needed to cover the floor.
Step-by-step explanation:
Width of floor = 4 feet 6 inches
Length of floor = 8 feet 3 inches
As we know,
1 foot = 12 inches
Therefore,
Width of floor = 4(12) + 6 = 54 inches
Length of floor = 8(12) + 3 = 99 inches
Area of floor = Length * Width

36 Inch = 1 yard
1 inch = 
5346 inches = 
148.5 square yards of floor covering will be needed to cover the floor.
