Question

Find the perimeter of the given triangle

Answer 1

ABC is similar to PQR

that means AC/PR is a constant = 12/ 6 = 2

AC= 2 PR

AB= 2PQ

BC= 2QR

Perimeter of ABC= AB+BC+ CA=

2PQ + 2 QR + 2PR= 2( PQ+ QR+ PR)

= 2( perimeter of triangle PQR )

Perimeter of ABC= 2( perimeter of PQR) = 2* 36 = 72

Answer : 72.
