Question

5. ALMN - APQR, 9 x A (APQR) = 16 x A (ALMN)
If QR = 20, then find MN​

Answer 1

Answer:

15cm

Step-by-step explanation:

According to theorem of equal ratio’s

A(∆LMN) = MN²

A(∆PQR) QR²

9 = MN²

16 20²

20² x 9 = MN² x 16

3600 = MN² x 16

MN² = 3600

16

MN² = 225

MN = √225

MN = 15cm
