Question

Rashmi made a rangoli design in a rangoli competition. She came first. She measured every part of her rangoli, it is a square of side 14cm . Semi circles are drawn with each side of square as diameter. Find area of shaded region

Answer 1

Answer:

what is the shaded region???????

Answer 2

Area of shaded region is 504 $cm^{2}$.

Step-by-step explanation:

given:    

     Side of the square 's' = 14 cm

     Radius of circle 'r' = 7 cm

According to the question.

   Now, Area of the square = s x s

          Area of the square = 14 x 14

          Area of the square = 196 $cm^{2}$

Area of four semi circles  =  4 x $\pi \times r^{2}$

Area of two circles = 4 x π x $7^{2}$

Area of two circles = 308  $cm^{2}$

Now, total area of shaded region =  308 + 196

                                                        = 504  $cm^{2}$
