Question

In the given figure, PQRS is a quadrilateral which circumscribes a circle with centre O. If PD=4cm, QB=3cm, RC=6cm and SD=5cm, then PQ is equal to

Answer 1

Step-by-step explanation:

ABCD is a quadrilateral and let O be the center of the circle inscribed in the quadrilateral.

AB, BC, CD and AD are the tangent to the circle at P, Q, R and S, AP = 9 , PB = 7 , QC = 5 and DR = 6

We know that the lengths of the two tangents from a point to circle are equal.

Thus, AP=AS=9 cm

BP=BQ=7 cm

CQ-CR-5 cm

DR DS-6 cm

Perimeter of quadrilateral ABCD=AB+BC+CD+AD

=AP+BP+BQ+CQ+CR+DR+DS+AS

=9+7+7+5+5+6+6+9
