Question

if ∆AbC ~∆PQR , ar(PQR) =100cm2 and AB/PQ=1/2 then ar(ABC) is?​

Answer 1

Answer:

25Cm2

Step-by-step explanation:

ar(ABC) /ar(PQR) = (AB/PQ) 2

ar(ABC) /100= (1/2)2

ar(ABC) /100= 1/4

ar(ABC) = 100/4

ar(ABC) = 25 cm2

Answer 2

Step-by-step explanation:

ar abc. x. 1²

---------- = -------- = --------- = 25 cm²

ar pqr. 100. 2²
