Answer:
154.88cm²
Step-by-step explanation:
⇒ Radius of semi-circle (r)= 14 –6 / 4 = 8 / 4 =2cm
⇒ Side of a small square 2r=2×2=4cm
⇒ Area of big square =(side)² =(14)²
=196cm²
⇒ Area of a small square =(side)² =(4)² =16cm²
⇒ Area of 4 semicircle =4× πr²/2 =4×3.14×(2)² / 2 =25.12cm²
∴ Area of shaded region = Area of a big square - Area of a small square - Area of a 4 semicircle.
∴ Area of shaded region=(196−16−25.12)cm²
=154.88cm²
