Answer question number 5 fast as fast as you can please
5. In the given figure, find the area of shaded region.
Dear Student,
Please find below the solution to the asked query:
Here portion added below square is not clear so we assume that is a semicircle with radius 7 cm
We know : Area of square = ( Side )2 , So
Area of given square = 142 = 196 cm2
We know exterior angle of square is at 90 and we know area of sector of circle =
Then,
Area of given sectors =
So,
Area of given two sectors = 2 ( 9.625 ) = 19.25 cm2
We know area of semicircle = , So
Area of given semicircle =
And we know area of circle = , So
Area of given circle =
Therefore,
Area of shaded part = Area of square + Area of two sectors + Area of semicircle - Area of circle = 196 + 19.25 + 77 - 154 = 138.25 cm2 ( Ans )
