Question

Given triangle ABC similer triangle PQR, if AB upon PQ=1/3,then find area ABC/area PQR

Answer 1

∵ Δ ABC ≈ Δ PQR

∴ Ar ( Δ ABC ) / Ar ( Δ PQR ) = ( AB/PQ)² 
( According to the theorem on similarity of triangles)

∴ Ar ( Δ ABC ) / Ar ( Δ PQR ) = ( 1/3)²

∴ Ar ( Δ ABC ) / Ar ( Δ PQR ) = 1 / 9
