Ahaan Oswaal ..
OR
Area of square ABCD= (14)² =196
Area of 4 semi circles= 4×1/2(πr²)
=2×3.14×2×2
=25.12cm²
Length of side of square inside the semi-circles=14-(3+3)-(2+2) =4cm
Area of square=(4²) =16cm²
Area of shaded region= Area of square ABCD- (Area of 4 semi circles + Area of square)
= 196-(25.12+16)
= 196-41.12
= 154.88cm²
Done :)
