the length of a retangle is twice the width.the area is 200yd^2??? Can someone help me please!!!!!find the lenght and width

math 
Julia,
L = 2w
W = w
A=Lxw
200= (2w) (w)
200 = 2w^2
200 = 2w^2
200 divided by 2 = w^2
100 = w^2
square root of 100 = w
w= 10
Therefore the length is 20 and the width is 10.
