Question

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is 21+ Zw = 16, where I

represents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of
the rectangle?
O 7 in.
O 8 in
9 in.
10 in

Answer 1

7 in

Explanation:

The sum of length and width is 16/2 = 8 inches. This means the length could be any value between 0 and 8 inches.

If it is 0 or 8 inches, then the area of the rectangle is 0, and its figure is indistinguishable from a line segment 8 units long.

We assume you want your rectangle to have non-zero area, so the appropriate choice is 7 inches.
