the table is_____ft wide and ______ ft. long.
PLEASE HELP

math algebra 
JJ,
length is twice the width
L = 2W
area is length times width.
72 = (2w(w)
72 = 2w^2
divide both sides by 2 to get 36 and then take the square root of 36 to find "w". double that value to find the length. Check by multiplying l times w to see if you get 72.
