Since its a similar triangle;
so, let A1 = the area of the larger triangle
A2 = the area of the smaller triangle
P1 = the perimeter of the larger triangle
P2 = the perimeter of the smaller triangle
by ratio & proportion:
A1 = 16*A2 ----(1)
(A1/A2) = (P1/P2)^2 ----(2)
substitute (1) into (2)
[(16*A2)/A2] = (P1/P2)^2
taking the sqrt. on both sides;
4P2 = P1
thus, the ratio is:
4:1 --- answer
