63 ${cm}^{2}$

______

step-by-step explanation:

In the given figure,

a hemisphere is inscribed in a rectangle.

now,

for rectangle,

length, l = 14 cm

breadth, b = 10 cm

therefore,

area, A = lb

=> A = 14 × 10

=> A = 140 ${cm}^{2}$

Now,

for hemisphere,

diameter = 14 cm

=> radius, r = 14/2

=> r = 7 cm

therefore,

area, A' = $π{r}^{2}/2$

=> A' = (22×49)/(7 × 2)

=> A' = 77 ${cm}^{2}$

Now,

area of shaded region, A" = A - A'

=> A" = 140 -77

=> A" = 63 ${cm}^{2}$
