area of rectangle = 50×14 = 700 cm^2

area of semicircle = 1/2 pie r^2= 1/2× 22/7 ×7×7 = 11×7 = 77 cm^2

area of quadrant = 1/2 of area of semicircle = 38.5 cm^2

area = 623- 38.5 = 584.5 cm^2

Answer 2

Answer:

steps are in picture

area of rectangle=700cm^2

area of half circle=77cm^2

area of given sector of r=7cm is 77/2=38.5cm^2

area of non shaded reason=77+38.5

=115.5cm^2

area of=area of. - area of non

shaded. rectangle. shaded

=700-115.5

=584.5cm^2

if your answer in fraction then you take 77/2 in the place of 38.5
