Question

a piece of wire is bent to form a square of area 121 cm^2 what is the length of each side of the quarter and what is perimeter of the square
​

Answer 1

Answer:

Area of squared wire =121cm  

2

 

⇒s×s=121

⇒ side of square =11cm

Perimeter of square =4×s

=4×11=44cm=Circumference of circular wire

⇒2π×r=44

⇒r=  

2π

44

​  

 

⇒r=7cm

Now, Area of Circular wire =π×r  

2

 

=  

7

22

​  

×7×7

=154cm  

2

 

So, area of the wire when bent in circular shape is 154cm
