Question

ABCD is a parallelogram and T is the midpoint of AD. If ar(quadrilateral ABCT)=45cm,then find at(∆TCD).

Answer 1

In ||gm ABCD,
∆TCD and ||gm ABCD are on same base CD and between same parallel AB and CD,
so,Ar(∆TCD)=1/2Ar(||gm ABCD)
Ar(∆TCD)=1/2×45
Hence,Ar(∆TCD)=22.5 cm².
Hope it helped u!
Pls,,mark as brainliest^_^.
