Answer:
10.5, [tex]10\frac{1}{2}[/tex], or [tex]\frac{21}{2}[/tex]
Step-by-step explanation:
To solve, you can use a variable (x) to represent the width.
The equation for area is A=L×W
So the Area is 820 and the length is 78.
820= 78w
Isolate the variable to solve.
w=10.5128....
If you round, it will be 10.5
10.5 as a fraction is [tex]10\frac{1}{2}[/tex] or [tex]\frac{21}{2}[/tex]
