- PQRS is a square. T&U are respectively,the mid - points of PS & QR.find the area of triangle OTS,if PQ=8cm,where O is the point of intersection of TU & QS
- ABCD is a parallelogram in which BC is produced to E suh that CE=BC.AE intersects CD at F.if ar(DFB)=3cm
^{2}find the area of the parallelogram ABCD.

^{2}find the area of the parallelogram ABCD.

1) Given : PQRS is a square with T and U as mid points of side PS and QR respectively and QS and TU intersect at point O.

Since T and U are mid points of PS and QR respectively

∴ TU || PQ ⇒ TO || PQ

Thus in ΔPQS, T is the mid point of PS and TO || PQ.
