Question

In figure, AP =2 cm, BQ = 3 cm and RC =4 cm, then find the perimeter of $\Delta ABC$

Answer 1

REF.Image.

As the know that two tangents drawn from an

external point to the circle are equal in length.

so,

$AR=AP=2cm$

$BQ=BP=3cm$

$RC=QC=4cm$

Perimeter $=AB+AC+BC$

$=(AR+RC)+(CQ+BQ)+(AP+BP)$

$=(2+4)+(4+3)+(2+3)$

$=6+7+5$

$=18cm$
