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?
possible answers: 25/9--1/6--5/3--9/25

the triangles are similar what is the ratio ( larger to smaller) of the area
possible answers: 25/9--15/9--5/3--9/25

please someone help me.

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

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