Answer 1

⠀⠀|| ☆.Solution.☆ ||

Given:-

• Length of rectangle = 12 cm
• width of rectangle = 11 cm
• Radius of circle = 2 cm

Find :-

• Area of shaded regions .

⠀|| ☆.Explanation.☆ ||

First , calculate area of rectangle

★ Area of rectangle = ( Length × Width )

➥ Area of rectangle = 12 × 11

➥ Area of rectangle = 132 cm²

Now, calculate area of circle

★ Area of circle = π.r²

where,

• r = Radius

➥ Area of circle = 3.14 × 2²

➥ Area of circle = 3.14 × 4

➥ Area of circle = 12.56 cm²

For shaded region,

If we subtract area of circle from area of rectangle , then we can find area shaded regions .

So,

★ Area of shaded region = Area of rectangle - Area of circle

➥ Area of shaded region = 132 - 12.56

➥ Area of shaded region = 119.44 cm²

Thus:-

• Area of shaded regions = 119.44 cm²
