1.	ALMN ~ APQR, 9 x A (APQR) =16 x A (ALMN),भाप का मान ज्ञात करो ।हल :
Answer» 9 × Area ( ∆PQR) = 16 × Area(∆LMN) Area of ∆LMN : Area of ∆PQR = 9:16 We know that, Area of two similar triangles is always Equal to square of their corresponding sides. Therefore, Area ( ∆LMN) / Area ( ∆PQR) = (MN/QR)² 9/16 = (MN)² / (20)² 9/16 = (MN)² / 400 (MN)² = 9×400/16 (MN) = √(9×400/16) MN = 3×20/4 MN = 3 × 5 = 15 cm Like my answer if you find it useful!

Answer»

9 × Area ( ∆PQR) = 16 × Area(∆LMN)

Area of ∆LMN : Area of ∆PQR = 9:16

We know that,

Area of two similar triangles is always Equal to square of their corresponding sides.

Therefore,

Area ( ∆LMN) / Area ( ∆PQR) = (MN/QR)²

9/16 = (MN)² / (20)²

9/16 = (MN)² / 400

(MN)² = 9×400/16

(MN) = √(9×400/16)

MN = 3×20/4

MN = 3 × 5 = 15 cm
