In /_\ABC , D, E, F are the mid-points of bar(AB) , bar(BC) , bar(CA) and if bar(AB) = 11 cm, bar(BC) = 9 cm, bar(CA) = 8cm. Find the lengths of bar(DE) , bar(EF) and bar(DF) .
In the given figure, AB|\|CD|\|EF given that AB=7.5 cm, DC=y cm, EF=4.5 cm, BC=x cm. Find the values of x and y.
In DeltaABC AC=12 cm , AB=5 cm and angleBAC=30^@ , then area of the DeltaABC is……………
