Answer 1

Answer:

Thanks for your question...

Your required answer :

• Area of square = a²
• 14 × 14
• 196 cm²

Now .

• Area of circle = πr²
• 3.14 × 3.5 × 3.5
• 38.465 cm²
• As there are 4 circles so we have to multiply area of 1 circle with 4.

Area of 4 circles :

• 38.465 × 4
• 153.86 cm²

The area of the remaining portion of the plate :

• Area of square - Area of 4 circles
• 196 - 153.86
• 42.14
