Let △ABC ~ △RPQ and 
=. If PQ = 4 cm , QR =6 cm and PR = 7 cm, then AC (in cm) is equal to :
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4.8
= 16/25
Then the ratio of their corresponding sides = 4 : 5
AB/RP = BC/PQ = AC/RQ.
AC/6 = 4/5
AC = 24/5 = 4.8 cm.
