GIVEN ↴
- DA parralel to AB
- DA parralel to ABDC =7 cm
- DA parralel to ABDC =7 cmCB=10 cm
- DA parralel to ABDC =7 cmCB=10 cmAB=13 cm
TO FIND↴
area of the quadrilateral ABCD
SOLUTION↴
Draw CMLAB
...AM=DC=7 cm
MB=AB-AM
=13-7
=6 cm
In rt. √d ∆CMB,
CM²=10²-6²
=(10+6)(10-6)
=16*4
CM² =64
CM=√64=8 cm
.Ar(ABCD)=Area of Trapezium
=1/2xheightxsum of parallel sides
=1/2x8x(13+7)
=4*20
=80 cm²
