Answer:

%age of shaded part = 73%

Step-by-step explanation:

Perimeter = 4(length)

Length = 40/4

L = 10 cm

Now

Finding the area of the shaded part:

= (10×10) - (3×10)/2 - (6×4)/2

= 100 - 15 - 12

= 85 - 12

= 73 cm²

Now Converting into %age

Area of square = 100 cm²

So

%age of shaded part = (73/100) × 100%

%age of shaded part = 73%
