Question

∆ abc ~ ∆pqr, a(∆abc) =81cm2, if ab=6, pq=12cm, find a(∆pqr)​

Answer 1

Step-by-step explanation:

A(∆ABC). AB^2

--------------= ----------. ----(theorem of areas of

A(∆PQR). PQ^2. similar triangle)

81. 6^2

--------. =. -------

A(∆PQR). 12^2

A(∆PQR) = 81×144

-----------

36

A(∆PQR)= 324 cm^2
