Let length be x and width be y.
We have x= 2y+1  (1)
Also xy = 28 (2)
Putting value of x from(1) in (2), we get
(2y+1)y = 28
2y^2 +y28 = 0
2y^2+8y7y 28 = 0
Or, 2y(y+4)7(y+4) = 0
Or, (2y7) (y+4) = 0
Or, y = 7/2, 4
Neglecting 4, we get width = 7/2 = 3.5 ft.
Length = 2*3.5+1 = 8 ft. Ans.
Kindly ACCEPT the answer.
