Question

traingle ABC similar to traingle PQR, 18× A(ABC) × A (PQR), If BC=28, then find QR​

Answer 1

Step-by-step explanation:

ΔΑΒC- ΔΡ

Area of A PQR Area of AABC AB)? = (QR/BC)2 = (PR/AC)2 = (PQI

Area of A PQR = 100 cm?

Area of A ABC = 64 cm?

BC = 4 cm

QR = ? !!

Area of A PQR / Area of AABC = BC)2 (QR/

=> 100 /64 = (QR/4)2 => 25 / 16 = QR?/16

=> QR? = 25

=> QR = 5 cm
