If the area of a rectangle is 8 square inches and length twice width what rectangle?

Length: 2x inches

Area of a rectangle is given by the formula:

```

Area = Length x Width

```

Substituting the values we know:

```

8 = 2x * x

```

Solving for x:

```

x = 2 inches

```

Therefore, the width of the rectangle is 2 inches and the length is 2 x 2 = 4 inches.
