Answer:
[tex]216=2w \times w[/tex]
Step-by-step explanation:
Assuming that the patio is a rectangle, we have
[tex]A= l\times w[/tex]
Where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Now let's assume that the length of the patio is double than the width.
[tex]l=2w[/tex]
So, the equation that represents this problem is
[tex]216=2w \times w[/tex]
Answer:
x(x+6)=216
Step-by-step explanation:
It would actually be x instead of w because in the equation, they are using x's.
The equation would then be solved by making the equation x^2+6x=216.
By completing the square using (b/2)^2, you would then get the width to be 12 and the length to be 18.
Hope this helps!
