Answer

Area of the figure = 8.5 square units

Step-by-step explanation

From the given figure, five composite plane shapes are possible.

Shape 1 is a parallelogram

Area of parallelogram = base x height

= 1 x 1

= 1 square unit

Shape 2 is a rectangle

Area of a rectangle = Length x Width

= 3 x 1

= 3 square units

Shape 3 is a rectangle

Area = 2 x 1

= 2 square units

Shape 4 is a triangle

Area of triangle = 1/2 x base x height

= 1/2 x 1 x 2

= 1 square unit

Shape 5 is a triangle

Area = 1/2 x 1 x 3

= 1.5 square units

The area of the given figure will be the sum of the areas of all the composite shapes, that is

Area of the figure = Areas of (shape 1 + shape 2 + shape 3 + shape 4 + shape 5)

= 1 + 3 + 2 + 1 + 1.5

Area of the figure = 8.5 square units
