Question

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is 2 l plus 2 w equals 16, where l represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle? 7 in. 8 in. 9 in. 10 in.

Answer 1

Answer: 7 inches

Explanation:

I took the test on this and scored 100%

Answer 2

7 in.

Explanation:

When 7 in. is used this is what happens

2(7) + 2(w) = 16 in.

14 + 2w = 16 in.

Because the 7 in. option leaves room for the value of the width unlike the others.
