Question

In the given figure, the side of square is 28cm and radius I'd each circle is half of the length of the side of the square, where O and O' are centres of the circle. Find the area of shaded area.
​

Answer 1

Answer:

Step-by-step explanation:

1708 cm sq.

Answer 2

Answer:

1708 cm²

Step-by-step explanation:

According to the figure

Area of shaded region = area of 2circles + area of a square - area of a semicircle

side=28cm

radius=14

so ,

area of a circle = $\pi r\x^{2}$

= $\frac{22}{7}$×14×14

=616cm²

∴area of two circles = 2×616

                                 = 1232 cm²

area of a square = s²

                           = 28×28

                           = 784cm²

area of a semicircle = $\frac{\pi\\r^{2} }{2}$

                                 =308 cm²

substitute the values in the above equation

area of shaded region = area of 2circles + area of a square - area of a semicircle

Area of shaded region = 1232 + 784 - 308

                                      =1708 cm²  

∴   area of shaded region of the given figure is 1708 cm² .
