Question

∆ABC ~ ∆PQR , if AB= 4cm , PQ=9cm and ar(∆PQR) = 162cm2 then ar ( ∆ABC)= ____ cm2?​

Answer 1

Step-by-step explanation:

AB /PQ = ∆ABC/∆PQR

put the values

4/9=∆ABC/162cm2

by cross multiplying & dividing it we get

∆ABC =27.5 cm^2

Answer 2

Answer:

If,∆ABC ~ ∆PQR

AB=4cm, PQ=9cm

then,

ABC/PQR=AB/PQ

=ABC/PQR=4/9

=ABC/162=4/9

9 ABC=648 $cm^{2}$

ABC= 648/9

THEREFORE, ABC=72 $cm^{2}$
