Question

The perimeter of two similar triangle AB and PQR are respectively 48 cm and 36 cm . If PQ=12cm ,then AB is

Answer 1

Answer:

as both triangles are similar then their perimeters will be in ratio

perimeter of ABC/perimeter of PQR

48/36=X/12

48×12=x×36

x=48×12/36

x=16

Answer 2

Answer:

AB = 16

Step-by-step explanation:

first we take 2 similar triangles

triangle ABC congurent to triangle PQR

AB/PQ

BC/QR

AC/PR = 48/36

if PQ = 12

then

48×12/36

= 16 cm
