AB=AC.......................... ( Tangents drawn from an external point)
Therefore, AC= 5 cm.
Also, PX=PB..................( Tangents drawn from an external point)------- {1}
QX=QC.................( Tangents drawn from an external point)-------{2}
Hence, Perimeter=
AP+PX+QX+AQ
= AP+PB+QC+AQ ---------------- USING {1} and {2}
= AB+AC
=2AB
= 2 X 5
=10 cm
