Answer 2

Answer:

The area of the enclosed place is 42 cm square.

Step-by-step explanation:

Given : Four circular cardboard pieces each of radius 7cm are placed in such a way that each piece touches two other pieces.

To Find : The area of the enclosed place?

Solution :

Area of square formed by joining the centers of four circles - Area of 4 equal quadrants i.e. forming a circle  

So,

Area =Area of square- Area of circle  

$A=l\times b-\pi r^2$

$A=14\times14-\frac{22}{7}\times7\times 7$

$A=196-154$

$A=42cm^2$

The area of the enclosed place is 42 cm square.
