Question

of
side them and the area
of shaded
B ​

Answer 1

Answer:

42 cm^2

Step-by-step explanation:

 Side of square = 14 cm.

    ⇒ Area of square = 14^2 cm^2  

                             = 196 cm^2

Side of square = diameter of 2 circles

⇒ 14 cm = diameter of 2 circles

⇒ 14/2 cm = 7 cm = diameter of 1 circle.

   It means, diameter of each circle is 7 cm.

Hence, radius of each circle is 7/2 cm = 3.5 cm

   Area of 1 circle = π( 3.5 cm )^2

        = π( 12.25 cm )^2

        = ( 22/7  * 12.25 cm )^2

        = 38.5  cm^2

As there are four circles of same radius, total area covered by circles = 4 * 38.5 cm^2 = 154 cm^2

   Therefore,

⇒ Shaded area = area of square - area of circles

         = 196 cm^2 - 154 cm^2

         = 42 cm^2
