The area of shaded region is 32 square units.
"The area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. The area is measured in square units such as square centimeters, square feet, square inches, etc."
To find the area of the shaded region
1. Find the area of the biggest square ([tex]A_{1}[/tex])
Formula for area of a square
[tex]A_{1}[/tex] = side × side
⇒[tex]A_{1}[/tex] = 10×10
⇒[tex]A_{1}[/tex] = 100 square units.
2. Find the area of the unshaded region ([tex]A_{2}[/tex])
[tex]A_{2}[/tex] = X(biggest square)+ 2.Y(smallest square)
⇒[tex]A_{2}[/tex] = [tex](6[/tex]×[tex]6)[/tex] + [tex]2(4[/tex]×[tex]4)[/tex]
⇒[tex]A_{2} =36+2.(16)[/tex]
⇒[tex]A_{2}=68[/tex] square units
3. Find the difference of [tex]A_{1}[/tex] and [tex]A_{2}[/tex]
Area of the shaded part = [tex]A_{1}[/tex] - [tex]A_{2}[/tex]
= 100-68
= 32 square units.
Hence, The area of shaded region is 32 square units.
