Answer:
perimeter of triangle PLM=56cm
Step-by-step explanation:
From the diagram,
L is the external point with tangents LN and LQ
hence, LN=LQ
Similarly, M and P are external points with respective tangents
so, PQ=PT =28cm
MN=MT
Perimeter of triangle PLM
= PL+LM+MP
= (PQ-LQ)+(LN+NM)+(PT-MT)
=PQ-LQ+LN+NM+PT-MT
=PQ-LN+LN+MT-MT+PT
= PQ+PT
=28+28
=56cm
