A side of one polygon is 18 meters and the corresponding side of a second similar polygon is 24 meters. If the perimeter of the
first polygon is 16 meters and it's area is 1000 square meters find the perimeter and area of the similar polygon
1 answer:
The perimeter of a polygon is proportional to its side so:
18 : 16
24 : p
p = 21.3 meters
Area is proportional to the square of the side of a polygon so:
18² : 1000
24² : x
x = 1,777.8 square meters
Note: The value of the perimeter should not be less than the length of one side. The data may be incorrect. Regardless, the method will be the same.
