Answer :
Area = length x width
length = 2 x width - 3
i.e. 65 = w(2w - 3)
2w^2 - 3w - 65 = 0
(w + 5)(2w - 13) = 0
w = -5 or w = 6.5
but width cannot be negative, hence
width = 6.5 ft
Length = 2 x 6.5 - 3 = 13 - 3 = 10 ft
length = 2 x width - 3
i.e. 65 = w(2w - 3)
2w^2 - 3w - 65 = 0
(w + 5)(2w - 13) = 0
w = -5 or w = 6.5
but width cannot be negative, hence
width = 6.5 ft
Length = 2 x 6.5 - 3 = 13 - 3 = 10 ft
