Answer 1

Answer:

260 cm^2

Step-by-step explanation:

Total Area = Area of rectangle -2*Area of quadrants + Area of Semicircle

Length = 20 cm

Breadth = 13 cm

Radius of given quadrants and Semicircle = 5 cm

$area = l \times b - 2 \times \frac{\pi {r}^{2} }{4} + \frac{\pi {r}^{2} }{2} \\ = 20 \times 13 - \frac{\pi {r}^{2} }{2} \: + \frac{\pi {r}^{2} }{2} \: \\ = 20 \times 13 \\ = 260 \: {cm}^{2}$

Answer 2

Answer:

Total Area = Area of rectangle -2*Area of quadrants + Area of Semicircle

Length = 20 cm

Breadth = 13 cm

Radius of given quadrants and Semicircle = 5 cm

= 260 sq. cm
