Question

triangle LMN similar to triangle PQR,9XA(triangle PQR)= 16×A (triangle LMN) if QR =20 then find the MN...​

Answer 1

Step-by-step explanation:

9 × A(∆PQR) = 16 × A(∆LMN) [Given]

Now, ∆LMN ~ ∆PQR [Given]

[Theorem of areas of similar triangles]

∴ MN/QR = 3/4 [Taking square root of both sides]
