Question

if triangle ABC similar to triangle PQR area of triangle ABC is equals to 81 CM square area of triangle PQR is equal to 144 CM square and and QR is equals to 6 CM then length of BC is​

Answer 1

Answer:

Triangle Abc area is =triangle PQR

then

given Triangle Abc area=81

Triangle PQR area=144

sides=6

area of triangle PQR= 1/2×base×height

144=1/2×6×h

144×2/1=6×h

72=6×h

72/6=h

12=h

Triangle ABC=Triangle PQR

bc=6

Answer 2

4.5CM is the answer for this question
