Answer

PQ-PT [Because tangents drawn from an external point to the circle are equal in length]

PL+LQ = = PM + MT

PL + LN = PM + MN ... (i) (LQ = LN, MT = MN)

[Because tangents drawn from an external point to the circle are equal in length]

Perimeter(PLM) PL + LM + PM

= PL + LN + MN + PM

= PL + LN + PL + LN [Using (i)] = 2(PL + LN)

= 2 (PL + LQ) = 2 × 28 = 56cm : LQ = LN =

MT = MN [Because tangents drawn from an external point to the circle are equal in length]
