Answer:

The dimensions are $16$ ft by $32$ ft

The quadratic equation is $W^{2}-256=0$

Step-by-step explanation:

we know that

the area of rectangle is equal to

$A=W*L$

where

L is the length side of rectangle

W is the width side of rectangle

in this problem

we have

$A=512\ ft^{2}$

$512=L*W$ -----> equation A

$L=2W$ ------> equation B

substitute equation B in equation A

$512=(2W)*W \\ 512=2W^{2} \\2W^{2}-512=0\\W^{2}-256=0$

$W=\sqrt{256}=16\ ft$

Find the value of L

$L=2W-----> L=2*16=32\ ft$
