Question

find the area of the shaded region in the given figure.ABCD is a square of side 10.5​

Answer 1

Answer:

first find the area of Square and then take 10.5/2as the radious and find its area and subtract circle from square

Answer 2

Answer:

Area of shaded region = 23.71 $cm^{2}$

Step-by-step explanation:

Given the side of square = 10.5cm

We know that-

The area of square(A) = $(side)^{2}$

                                    = $(10.5)^{2}$

$A = 110.25 cm^{2}$

From figure- there is a circle inside the square whose diameter is equal to side of square.

Diameter = 10.25

Radius of circle = $\dfrac{Diameter}{2}$

                         = $\dfrac{10.5}{2}$

Radius of circle r = 5,25 cm

Area of circle = $\pi r^{2}$

                      = 3.14 ×$(5.25)^{2}$

                      = 3.14 × 27.25

Area of circle = 86.54 $cm^{2}$

Area of shaded region = Area of square - Area of circle

                                      = 110.25 - 86.54

                                      = 23.71

Area of shaded region = 23.71 $cm^{2}$
