The perimeters of two similar triangles, GST and FAX, are 48 cm and 36 cm, respectively. If FA = 12 cm, then GS is:
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 16 cm.
FA/GS = Perimeter of ΔFAX/Perimtere of ΔGST
12/GS = 36/48
⇒ 1/GS = 3/48 = 1/16
⇒ GS = 16 cm
