Question

In the given figure, ABCD is a square of side 14 cm. Find the area of the shaded region in the given figure.

Answer 1

Area of the square = ${\mathrm{Side}}^2={14}^2=196\mathrm{sq}.\mathrm{cm}$

Area of the circles = $4\times \mathrm{\pi }\times 3.5\times 3.5=154\mathrm{sq}.\mathrm{cm}$

Area of the shaded region = Area of the square $-$ Area of four circles
$$\begin{gathered} =196-154 \\ =42{\mathrm{cm}}^2 \end{gathered}$$
