Answer:

Area = 6.6 cm²

Explanation:

Area of the shaded region =

Area of Rectangle - Area of Trapezoid - Area of circle - Area of Triangle

Area of rectangle = Length x Breadth

= 3 x ( 1.5 + 2 + 1.5)

= 3 x 5

= 15 cm²

Area of the trapezoid = h x ( a + b )/2

= 1.5 x ( 3 + 1)/2

= 1.5 x 2

= 3 cm²

Area of the circle = π x r²

= 3.14 x 1 [diameter, d = 2 cm, r = d/2 =1]

= 3.14 cm²

Area of triangle = (1/2) x base x height

= (1/2) x 3 x 1.5

= 2.25 cm²

Area of the shaded region = 15 - 3 - 3.14 - 2.25

= 6.61 cm²

= 6.6 cm ² [ round to nearest tenth ]
