a large triangle is 15ft and the small triangle is 9ft.

the triangles sre similar what is the ratio (larger to smaller) of the perimeters?

the triangles are similar what is the ratio ( larger to smaller) of the area

• geometry -

a. P1/P2 = S1/S2 = 15Ft/9Ft = 5/3.

b.A1/A2=(S1/S2)^2=(15/9)^2=(5/3)^2=25/9

• geometry -

1. 5/3
2.25/9

:D ^_^
