The length of the rectangle is 3 times its width. The perimeter of the rectangle is 16 inches.
.
Which of the following is a reasonable length for this rectangle?

Since length is three times, hence it is 6 inches.

let the width be x.

then, length= 3x

perimeter= 16 inches.

perimeter of a rectangle = 2( L+B)

2(3x+x)=16.

3x+x= 16÷2

4x= 8

x= 2

since length=3x

hence, 3×2= 6 inches

my answer is$ 12

step-by-step explanation:

because 15 -2=12

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
