From a circular card sheet of radius `14 cm,` two circles of radius `3.5 cm` and a rectangle of length `3 cm` and breadth `1cm` are removed. (as shown in the adjoining figure). Find the area of the remaining sheet. (Take `pi=22/7`)

Explanation

To find the area of the remaining sheet after removing two circles and a rectangle from a circular card sheet, we can follow these steps:

### Step 1: Calculate the area of the circular card sheet.
The formula for the area of a circle is:
\[ \text{Area} = \pi r^2 \]
Given that the radius \( r = 14 \) cm and \( \pi = \frac{22}{7} \):
