5 meters square. I think it's only half a square meter, or .5 sq. meters.
The length of the rectangle in question is 12 meters, and the width of the rectangle is 6 meters.We solve this by knowing that the area of a rectangle is equal to the length (l) times the width (w). That formula looks like this:Arectangle = l x wWe are told that the length is twice the width. Here's that idea in the form of an equation:l = 2wSince the length is twice the width, we can substitute the 2w for the l in the first equation. It looks like this:Arectangle = 2w x wNow we add the fact that the area was given as 72 meters2. and put it all together. It looks like this:72 meters2 = 2w x w72 meters2 = 2w236 meters2 = w2sqrt 36 meters2 = w6 meters = wWe have our width as 6 meters. The length is twice that, or 6 meters x 2 = 12 meters. There are our length and width. Let's check our work.Area = length (12 meters) times width (6 meters) = 12m x 6m = 72 m2Our work checks.
