ANSWER:

Step-by-step explanation:

Area of shaded portion inside the SQUARE = Area of square - Area of circle

a= side of square = 14cm, r= radius of circle= a/2 = 7cm

⇒a² - πr² = (14)² - 22×7×7/7= 196-154= 42cm²

Area of shaded REGION inside the second square= Area of square

a= side of square= hypotenuse of triangle

 = √(20)²+(5)² = √400+25 = √425 = 5√17cm

Area= (5√17)² = 25×17= 425cm²
