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

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
