B. 8 inches
C. 6 inches
D. 7 inches

Answer 1

It can be 8 inches since 8x2+6x2=28

Answer 2

Option B - 8 inches.

Explanation:

Given : A rectangle is no more than six inches wide, and its perimeter measures 28 inches.

To find : At least how long is the rectangle?

Solution :

The perimeter of the rectangle is given by

`P=2(l+b)`

Where, P is the perimeter P=28 inches.

l is the length of the rectangle

b is the breadth of the rectangle b=6 inches.

Substitute the value in the formula,

`28=2(l+6)`

`\farc{28}{2}=l+6`

`14=l+6`

`l=14-6`

`l=8`

Therefore, The length of the rectangle is at least 8 inches.

So, Option B is correct.
