THe length of a rectangle is twice the width. The area is 200yd^2. What is the length and width. Is this right
L=20
w=10

L * W = 200
L = 2W
Substitute 2W for L in the first equation and solve for W. Once you find W, insert that into the second equation to find L.
I hope this helps. Thanks for asking. 
well check it
check #1, yes, length is twice width
check #2, yes, the area is 20*10 = 200
however remember the units
20 Yards by 10 yeards
