Answer:

48.5 cm

Step-by-step explanation:

Let's see the formulas for areas of the shapes

Rectangle = length * width

Square = side^2

Triangle = 1/2(base*height)

Let's calculate area of rectangle first since it's easiest

Length  = 8cm

Width = 4cm

8*4 = 32 cm

Now, let's get area of square.

3cm * 3cm = 9cm

Now, the triangle.

Because one side of the square is 3cm, all of its sides are 3cm, therefore the base of the triangle = 3cm

The height is 8-3 = 5cm

Area of triangle = 1/2(b*h) = 1/2(5*3) = 15/2= 7.5cm

Add up all the areas we got earlier...

Area of Shape = 32cm + 9cm + 7.5 cm = 48.5cm
