Question

Can't we do it like this
1st take out the area of rectangle then divide it by the area of one disc .please give me answer in this form only ​

Answer 1

Step-by-step explanation:

First, Length of the Rectangle (l) = 11 cm

Breadth of the rectangle (b) = 2 cm

therefore, Area of rectangle = l × b = 11 × 2 = 22 sq.cm

Now,

Diameter of circle = 0.5 cm

therefore, radius will be 0.5/2

Now, area of circle= πr^ 2

= 22/7 × 0.5/2 × 0.5/ 2 = 2. 75/14

Now, total no. of discs can be prepared = area od rectangle/ Area of circle = 22/ 2.75/14 = 22/ 275/ 1400 = 22 × 1400 / 275. ( terms will be reciprocate)

= 56 × 2 = 112 ( by simplification)

Therefore, 112 discs will be prepared

Hope this will help you, Thank you!
