Question

triangleABC ~ triangle PQR and A (triangleABC) = 81²cm. If AB=6cm
P Q = 12 cm find A(trianglePQR)​

Answer 1

∆ABC~∆PQR

A(∆ABC) AB^2

------------ = -----

A(∆PQR) PQ^2

81 36

------------- = -----

A(∆PQR) 144

A(∆PQR) = 324^2 cm

Answer 2

Answer

∆ABC ~ ∆PQR

A(∆ABC). =. AB^2

--------------. -----------

A(∆PQR). PQ^2

81. =. 36

-------------. --------

A(∆PQR). 144

A(∆PQR). =. 324^2
