Answer 1

104 square meters

Explanation:

Make sure all the units are same and consistent!!

The shape of the shaded region = Trapezium

h = Perpendicular height of trapezium

= 16 m

∴Area of shaded region = Area of trapezium

=
`(1)/(2)` × (Sum of parallel sides) × h

=
`(1)/(2)` × [(9 + 4) m] × (16 m)

=
`(1)/(2)` × (13 m) × (16 m)

∴Area of shaded region = 104
`m^(2)`

= 104 square meters
