Question

given triangle ABC similar to triangle PQR, IfAB/PQ=1/3,then find area of triangle ABC/area of triangle PQR

Answer 1

hey mate!!
given: triangle ABC is similar to triangle PQR
and AB/PQ=1/3

ar of triangle ABC/ar of triangle PQR=AB^2/PQ^2. (by area theorem of similar triangles)
so, ar of triangle ABC/ar of triangle PQR=1^2/3^2=1/9

hope it helped!
