In quadrilateral PQRS, RM bot QS, PN bot QS and QS = 6cm. If RM = 3 cm and PN = 2 cm, then the area of PQRS is: चतुर्भुज PQRS में, RM bot QS, PN bot QS तथा QS = 6 सेमी है | यदि RM = 3 सेमी तथा PN = 2 सेमी है, तो PQRS का क्षेत्रफल कितना होगा ?

In the given figure, QS bot PR, RT bot PQ and QS =RT Is triangleQSR =~ triangleRTQ ? Give reason. (ii) Is anglePQR = anglePRQ ? Give reason.

trianglePQR, angleQ=90^(@), PQ=12, QR=5, QS is a medium find l(QS).

PQRS is a parallelogram in which PR is perpendicular to QS. If PR=8cm and QS=6 cm, then find PS
