Danielle built a rectangular dog run that is 888 feet wide and has an area of 208 square feet.
what is the length of danielle’s dog run?

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.

A= the square root of 3“if letters are anything like people, they’re all equal and deserve to be treated equally.”
