Answer:
61%
Explanation:
Area of square:
=a²
=12²
=144
Area of two quarter circles:
=2(¼×π×r²)
=2(¼×π×6²)
=2×28.72
=56.55
Finding the percentage:
=(56. 55÷144)×100
=0.3937×100
=39.27
subtract 100% by 39.27% to find the percentage of how much is shaded
=100-39.27
=60.73
=61 (rounded off to the nearest whole percent)
