What is the perimiter of triangle ABC?

Answer 1

A) 15 inches
B) 70 inches
C) 76.67 inches
D) 88.75 inches

Answer 2

For similar triangles, the ratio of the scale factor is equal to the ratio of the perimeters.
PQ and AB are corresponding sides.
PQ is to AB as perimeter of triangle PQR is to perimeter of triangle ABC

13/32.5 = 28/P where P is perimeter of triangle ABC and 28 is the perimeter of triangle PQR
P = [28*(32.5)] / 13
P = 70 inches
