If the rectangle is up-scaled (enlarged) perimeter will be $252 f t$ $252 ft$
If the rectangle is down-scaled (smaller) perimeter will be $20.6 f t$ $20.6 ft$

Explanation:

Since both the length $and$ $and$ the width are scaled by $3.5$ $3.5$ , the perimeter is also scaled by $3.5$ $3.5$

So upscale $P = 3.5 p = 3.5 \times 72 f t = 252 f t$ $P=3.5p=3.5xx72ft=252ft$

Downscale $P = \frac{p}{3.5} = 20.6 f t$ $P=p/3.5=20.6ft$
