Ответ:
given the side of a large triangle is 15ft and the side of a small triangle is 9ft.
we know the following facts about similar triangles : -
if scale factor (k) is the ratio of side of large triangle to the side of smaller triangle, then
1. ratio (larger to smaller) of the perimeters = k
2. ratio (larger to smaller) of the areas = k²
now, scale factor of given similar triangles would be side of larger triangle over side of smaller triangle.
scale factor, k =![\frac{15}{9} =\frac{5}{3}](/tex.php?f= \frac{15}{9} =\frac{5}{3} )
so, ratio (larger to smaller) of the perimeters = k =
.
ratio (larger to smaller) of the areas = k² =
.
