Answer 1

Answer:

Radius of circle = 3 cm.

Length of rectangle = 15 cm.

Breadth of rectangle = 6 cm.

Area of rectangle – [Arae of I + II + 1/2III] circles.

= 90 - 5/2 × πr2

= 90 – 5/2 × 3.14 × 32

Answer 2

Answer:

Radius of circle = 3 cm

Length of rectangle = 15 cm

Breadth of rectangle = 6 cm

Area of rectangle – [Arae of I + II + 1/2III] circles

= 15 6 – (Ar. of 2 ½ circles]

= 90 - 5/2 × πr2

= 90 – 5/2 × 3.14 × 32

= 90 – 70.65

= 19.35 cm2
