Answer:
area of whole figure (square)=l²
= 4²
= 16cm²
dia of center circle=2cm
radius= 2/2=1cm
area of center circle= πr²
= 22/7 ×(1)²
= 22/7× 1
≈ 3.14cm²
if we join all the sectors in the corners it will form a circle
area of circle= πr²
= 22/7×(1)²
= 22/7×1
≈ 3.14cm²
area of unshaded area= 3.14+3.14
= 6.28cm²
area of shade portion= whole - unshaded
= 16 - 6.28
= 9.72cm²
