Step-by-step explanation:
a. Given that the area's are in the ratios 16:81.
-Area is two-dimensional while perimeter is one-dimensional
=>The perimeter's of the two polygons will vary in a ratio equal to the square root of their area's ratio:
We use the perimeter ratio to find the perimeter of the larger polygon:
Hence, the perimeter of the larger polygon is 954 ft
b -Given the area of the larger polygon is 4779 ft2, the smaller polygon can be determined using the area ratio 16:81
Hence, area of the smaller polygon is![944 \ ft^2](/tpl/images/0574/4333/0442d.png)
