Answer:
Answer
(i) Its seen that,
Total area of the figure = Area of trapezium ABCD + Area of rectangle GAFE
Now, Area of trapezium ABCD
=
2
1
× (Sum of parallel sides) × (height)
=
2
1
×(AB+CD)×(AF+FD)
=
2
1
×(5+3)×(5+4)
=

1
×8×9=36cm
2
Area of rectangle GAFE=Length×Breadth
=2×5=10cm
2
Hence,
Total area of the figure =36+10 cm
2
=46 cm
2
(ii) Its seen that,
Area of given figure = Area of rect. ABCD + Area of parallelogram BIHJ + Area of rectangle EFGH
Now, Area of rectangle ABCD=Length×Breadth
=AD×CD
=9×2
=18cm
2
Area of rectangle EFGH=Length×Breadth
=(EJ+JH)×EF
=(7+2)×2=7×2=18cm
2
Area of parallelogram BIHJ=2×5=10cm
2
(Since distance between BI And HJ=9−2−2=5cm)
Hence
Total area of the figure =(18+18+10)cm
2
=46cm
