Danielle built a rectangular dog run that is 888 feet wide and has an area of 208 square feet.
umka2103 [35]
Let us assume the length of the rectangle = x
Width of the rectangular dog run = 888 feet
Area of the rectangular dog run = 208 square feet
We already know
Area = Length * Width
Length = Area/Width
           =  208/888 feet
           = 0.23 feet
So the length of the rectangular dog run is 0.23 feet. Since you have commented that you made a mistake in giving the question so the answer will also definitely change but the procedure will remain the same.
