To find the length of the floor of the rectangular deck, you can use the formula for the area of a rectangle, which is: Area = Length x Width Given that the area is 600 square feet and the width is 20 feet, you can substitute these values into the formula: 600 = Length x 20 To find the length, you need to divide the area by the width: Length = Area / Width Length = 600 / 20 Length = 30 ft Therefore, the length of the floor of the rectangular deck is 30 feet. So, the correct answer is C. 30 ft.
