Question

The scale factor of 2 similar polygons is 3:4. If the perimeter of the large polygon is 200, what is the perimeter of the small polygon?

Answer 1

perimeter is a linear measurement, so

perimeter of large / perimeter of small = 3/4
200/small = 4/3
4small = 600
small = 600/4
= 150

check"

150/ 200
= 3/4

Answer 2

second line should have been
perimeter is a linear measurement, so

perimeter of large / perimeter of small = 4/3

The rest stays the same
