Question

the areas of two similar triangles ABC and PQR are in the ratio of 9:16 if BC is=4.5 cm find. the length of QR​

Answer 1

Answer:

Step-by-step explanation:

Area(∆ABC)/Area(∆PQR)=BC^2/QR^2

=>9/16=(4.5/QR)^2

=>√9/16=4.5/QR

=>3/4=4.5/QR

=>3QR=4.5×4

=>QR=4.5×4/3

=>QR=1.5×4

=>QR=6.0cm

Answer 2

Answer:

QR = 6cm

Step-by-step explanation:

The length of QR is 6cm
