Question #ff732

Answer 1

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

Explanation:

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

So upscale `P=3.5p=3.5xx72ft=252ft`

Downscale `P=p/3.5=20.6ft`
