Question

2) Find the area of the shaded portion in the figure given below. 14 cm 14 cm ​

Answer 1

Answer:

Answer:Area of square = (14 cm)2 = 196 cm2

Answer:Area of square = (14 cm)2 = 196 cm2Radius of each circle = cm.

Answer:Area of square = (14 cm)2 = 196 cm2Radius of each circle = cm.Area of 4 circles =

Answer:Area of square = (14 cm)2 = 196 cm2Radius of each circle = cm.Area of 4 circles =Area of shaded region = Area of square - Area of 4 circles.

Answer:Area of square = (14 cm)2 = 196 cm2Radius of each circle = cm.Area of 4 circles =Area of shaded region = Area of square - Area of 4 circles.= 196 - 154 = 42 cm2

Answer 2

Given:

Side of square = 14cm

To Find:

Find the area of the shaded portion in the figure given.

Solution:

We know that,

Area of a square = side x side

Area of a circle = π$r^{2}$

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

Here, we have

Side = 14 cm

Radius = side/2 = 14/2 = 7 cm

So,

Area of square = side x side = 14 x 14 = 196 $cm^{2}$

Area of Circle = $\frac{22}{7} * 7^{2}$ = 22 x 7 = 154$cm^{2}$

Area of shaded region = 196 - 154 = 42$cm^{2}$

Hence, the area of the shaded portion in the figure given 42 $cm^{2}$.
