[ Answer ]
[tex]\boxed{Width \ = \ 31\frac{19}{91} \ Ft^{2}}[/tex]
[ Explanation ]
Area = 1420
Width = [tex]45\frac{1}{2}[/tex]
Area For Rectangle: Length · Width
Use division to find width:
1420 ÷ [tex]45\frac{1}{2}[/tex]
Convert mixed numbers to fractions:
1420 = [tex]\frac{1420}{1}[/tex]
[tex]45\frac{1}{2}[/tex] = [tex]\frac{91}{2}[/tex]
[tex]\frac{1420}{1}[/tex] ÷ [tex]\frac{91}{2}[/tex]
Use mixed multiplication:
[tex]\frac{1420*2}{1*91}[/tex]
= [tex]\frac{2140}{91}[/tex]
Simplify:
= [tex]31\frac{19}{91}[/tex]
[tex]\boxed{[ \ Eclipsed \ ]}[/tex]
