Question

Find the area of the shaded region of the square.

Answer 1

Area

Area of a square

The formula in finding the area of a square is $\tt A = {s}^{2}$

• $\tt A = {s}^{2}$
• $\tt A = {14cm}^{2}$
• $\tt A = {196cm}^{2}$

Area of a circle

The formula in finding the area of a circle is $\tt A = \pi r^2$

• $\tt A = \pi r^2$
• $\tt A = 3.14\times {7cm^2}$
• $\tt A = 3.14 \times 49cm$
• $\tt A = {153.86cm^2}$

Area of a shaded region

• $\tt A=A-A$
• $\tt A= {196cm}^{2}- {153.86cm^2}$
• $\tt A= {42.14cm}^{2}$

Therefore, the area of the composite figure is 42.14cm²

Answer 2

Answer:

42$cm^{2}$

Step-by-step explanation:

area of the square=14*14(l*w)

                              =196 $cm^{2}$

radius=14/2

         =7 cm

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

                           =$\frac{22}{7}$*7*7

                          =154 $cm^{2}$

area of the shaded part =196-154

                                        = 42$cm^{2}$
