Question

If triang if triangle ABC similar to triangle pqr is equal to 6 cm find the perimeter of triangle pqr

Answer 1

hii mate !

Given: triangle ABC ∼ triangle PQR,  perimeter of triangle ABC = 32cm, perimeter of triangle PQR = 48cm and PR = 6cm 
since the y are similar, 
AB/PQ = BC/QR = AC/PR 
AC/PR = perimeter of triangle ABC/perimeter of triangle PQR 
AC/6 = 32/48 
AC*48 = 6*32 
therefore AC = 4cm 

hope it helps !!☺☺☺
