Question

Can someone help me with this problem and show work please !

Answer 1

Answer: Length - 20, Width - 10

Explanation:

First we will use the formula to find area:

Area = Length * Width --- However, since it's double the length we will do 2Length.

Area = 2x*x

Given Area = 200

Next we will solve to find Width:

`2x^(2) =200`

Divide by 2:

`x^(2) =100`

Take square root:

`x=10`

Width = 10

Now we multiply 10 by 2, as length is twice it's width:

`2*10=20`

Length = 20

Final answer: Width = 10, Length = 20

I hope this helps!
