Area of wall to be covered = Length * Breadth = 27ft * 9ft
Area of Each Panel = 3ft * 3ft = \(9 ft^2\)
Cost of each panel, or cost for area of the panel (\(9 ft^2\)) = x dollars
Total Number of Pane;s required =\(\frac{ Area of wall }{ Area of Panel}\) = \(\frac{27ft * 9ft}{ 9 ft^2}\) = 27 panels
Cost of one panel = x dollars
Cost of 27 panels = 27*x dollars
So, Answer is C.
Hope it helps!
