In a parallelogram PQRS. The Altitude corresponding to sides PQ and PS are respectively. 7 cm and 8 cm find PS, if PQ=10 cm.

WXYZ is a parallelogram with XP⊥WZ and ZQ⊥WX. If WX = 8 cm, XP=8 cm and ZQ=2 cm, find YX.

The base BC of triangle ABC is divided at D so that BD=$\displaystyle \dfrac{1}{2}$  DC. Area of △ABD=

In △ABC,D is the mid-point of AB.P is any point of BC.CQ∥PD meets AB in Q. Then area of (△BPQ) is equal to

In the figure, compute the area of quadrilateral ABCD.

In the figure, ∠AOB=90°,AC=BC,OA=12 cm and OC=6.5 cm. Find the area of △AOB.

BD is a median of a triangle ABC. F is a point on AB such that CF intersects BD at E and BE = ED. If BF = 5 cm, BA is equal to 5k then k is A 1

In a △ABC,E is the mid-point of median AD. Then area of ( △BED) is equal to k/4 times area of Δabc

ABC is a triangle in which D is the mid-point of BC and E is the mid-point of AD. Find the ratio of the area of △BED and area of △ABC.

The figure formed by joining the consecutive mid-points of any rhombus is always

In the given Figure, ABCD,DCFE and ABFE are parallelograms. then ar(ADE) = ar(BCF).

In fig, ABCD is a parallelogram and BC is produced to a point Q such that AD=CQ. If AQ intersect DC at P, then ar(BPC)=ar(DPQ).

ABCD is a trapezium with AB∥DC. A line parallel to AC intersects AB at X and BC at Y. then ar(△ADX)=ar(△ACY)

In fig, ar(DRC)=ar(DPC) and ar(BDP)=ar(ARC). then both the quadrilaterals ABCD and DCPR are trapeziums.

The side AB of a parallelogram ABCD is produced to any point P. A line through A and parallel to CP meets CB (produced) at Q and then parallelogram PBQR is completed (figure). Find ar(ABCD) : ar(PBQR).
