Answer:
area of triangle = 1/2 × base × height
base = diameter of semicircle = 14cm
height = radius of semicircle = 7 cm
so, area = 1/2 × 14 × 7 = 49 sq. cm
now
area of semicircle = π×r×r/2
22/7 × 7 × 7 /2
= 77 sq.cm
area not occupied by triangle =
area of semicircle - area of triangle
77 - 49 = 28sq.cm
