PQRS is a rectangle. If PQ+QR=7 and PR+QS=10, then find the area of PQRS.
In āPQR, PQ=QR=PR and QSā„PR, PUā„QR and RTā„PQ. Then āPQR is symmetrical about
PQRS is a quadrilateral in which diagonals PR and QS intersect in O.
Find the correct relation between perimeter and diagonals of the quadrilateral.
In Fig. PQRS is a quadrilateral in which diagonals PR and QS intersect in O. Show that: (i) PQ + QR + RS + SP >PR + QS (ii) PQ + QR + RS + SP <2 (PR + QS)
