Question

∆PQR ~∆ABC , PQ=4 , QR=5, PR=6 if perimeter of ∆ABC is 60cm find each side of ∆ABC

Answer 1

Answer:

ABC sides = 16cm , 20cm , 24cm

Step-by-step explanation:

Acc to qstion. the length of sides of PQR is 4 , 5 , 6

and both are similar traingles ..therefore ....

let the length of each side be of triangle ABC... 4x , 5x , 6x

now

4x +5x+ 6x = 60

15x = 60

x = 60/ 15

x= 4

thus each side of ABC is ...16cm , 20cm , 24cm
