Question

Find the area of the shaded portion in each of the following figures :​

Answer 1

Answer:

2016 cm square

Step-by-step explanation:

this figure is made up of 4 semi-circles and one square.

So, as 4r(r = radius)

4r = 56

r = 56/4 = 14

As the radius is 14

$circle \: area\: \pi {r}^{2}$

$\frac{22}{7} \times 14 \times 14 = 616$

as it is made up of four semi-circles or two circles , it doubles itself now or

$616 \times 2 = 1232$

The square:

The square's side is made up of 2 radii or 28 cm

Square's area is

$28 \times 28 = 784$

Total area:

1232 + 784 = 2016

$area \: is \: written \: in \: unit \: square \: here \: unit \: is \: cm$

So, the answer is:

${2016 \: cm}^{2}$
