Question

ABC~∆PQR,BC=4cm और QR=7cm, तब ABCका क्षेत्रफल: PQR का क्षेत्रफल ​

Answer 1

Answer:

16:49

Step-by-step explanation:

67+75+866+97665-855

Answer 2

Given:

ABC~∆PQR

BC=4cm

QR=7cm

In two similar triangles, the ratio of their areas is the square of the ratio of their sides

$\frac{ar(ABC)}{ar(PQR)}= \frac{BC}{QR}$

$\frac{arABC}{arPQR}=(\frac{4}{7} )^{2} \\\frac{arABC}{arPQR}=\frac{16}{49}$

Hence area ΔABC:area of ΔPQR=16:49
