Answer:
area = 770 cm²
Step-by-step explanation:
semi circle back ith radii 7
area =πr²/2=22/7×14×14/2=77 cm²
same another semi circle area = 77cm² ( whose radius = 7)
area big semi circle = πr²/2 = 22/7×14×14/2 = 308
in same way big circle with radius 14 = 308
total area of shaded region = 308+308+77+77= 770cm²
