A rectangle has a length of 3 inches and a width of 5 inches. How would the

perimeter and the area of the rectangle change if one of the dimensions were tripled?

How would the perimeter and the area change if both dimensions were halved?

Based on these numbers, is it possible to know how the perimeter and the area of

any rectangle would change if one dimension were doubled? How about if both were

doubled? If it is possible, explain how it would change

If you triple any of the 2 dimensions for a rectangle with a length if 3 inches and with of 5 inches, the perimeter would be the same for both ways you triple it. If both dimensions are halved then the rectangle would be half the size it originally was. If one of the dimensions is doubled, the perimeter would be 30 inches for both ways if you double one or the other. If both dimensions are doubled, it would be double the perimeter of if you were to only double one side, so it would be 60 in.
