Oksanka [162]

Answer:

width = 3.5 feet        length = 8 feet.

Step-by-step explanation:

 W=x

L=2x+1

Area=(2x+1)x=28

2x^2+x=28

2x^2+x-28=0

 (2x-7)(x+4)=0

x=3.5,-4.  It should be a positive number so W=3.5

2x+1=8          2x3.5=7     7+1 = 8    L=8

That area is 28 ft^2

width is 3.5 feet and length is 8 feet.
