Nathalia Conway · Answer 1

Let l and w be the length and width, respectively. Given that length is 3 inches greater than the width, it can be expressed as w + 3. Tamara has 26 inches of ribbon for the border which means that the perimeter of the rectangle should be 26. For rectangles,

P = 2L + 2W

Substituting the known values,

26 = 2 (w + 3) + 2w

Simplifying,

26 = 4w + 6

Thus, w is 5 inches and length is 8 inches.
