Answer 1

Answer:

(c) 4:1

Step-by-step explanation:

given that. : PQR and QMR are equilateral triangles.and M is the mid of QR.

∆PQR and ∆QMR equilateral triangles since all angles are 60° and hence they are similar triangles .

Ratio of areas af similar triangle is equal to ratio of square of their sides .

so now,

p(∆QMN)/P(∆PQR)=QR^2/QN^2

p(∆PQR)/P(∆QMN)=(2BD)^2/(BD)^2.

since QR = 2 QN

p( ∆PQR)/A(QMN). = 4:1.

Answer 2

Answer: PQR and QMR are equilateral triangles.and M is the mid of QR.

∆PQR and ∆QMR equilateral triangles  

p(∆QMN)/P(∆PQR)=QR^2/QN^2

p(∆PQR)/P(∆QMN)=(2BD)^2/(BD)^2.

since QR = 2 QN

p( ∆PQR)/A(QMN). = 4:1.
