Answer:

Explanation:

Perimeter of Square = 40 cm

4*side = 40

side = 40/4

side = 10 cm

Area of shaded region= Area of square - [Area of triangle 1 + Area of triangle 2]

$=[side*side]-[(1)/(2)*b*h+(1)/(2)*b*h]\\\\=[10*10]-[\frac{1}2}*3*10+(1)/(2)*10*6]\\\\=100-[3*5+5*6]\\\\=100-[15+30]\\\\=100-45\\\\=55cm^(2)\\$

Percentage = (55/100)*100=55%
