The top of a rectangular dining room table is twice as long as it is wide. dimensions of the table if the area is 72 ft^2

the table is_____ft wide and ______ ft. long.

• math algebra -

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.
