Question

In the given figure find the area of shaded portion ABCD is a square of side 10 cm. plz solve
​

Answer 1

Explanation:

here we have side 10 CM of a square.

So by using the formula of area of square = side× side

we got the answer 100cm square

Answer 2

$\sf\small\underline \orange{Given:-}$

$\sf \rightarrow \: side \: of \: square \: = 1cm$

$\sf\small\underline \orange{Solution:-}$

$\dashrightarrow\sf \: Area \: of \: the \: square \: ABCD = 10 × 10 = 100cm^2$

$\dashrightarrow \sf Area \: of \: the \: region \: R= Area \: of \: the \: region \: R.</p><p></p><p>$

=Area of square-Area of two semicircles of radius 5cm

$\sf= 100 - 2 [ \frac{1}{2} π (5)^2 ] = 100 -25π$

=Area of square -Area of two semicircle of radius 5cm.

$\sf= 100 - 2 [ \frac{1}{2} π (5)^2 ] = 100 - 25π$

So, Area of the shaded region.

Solving,

$\sf \: = 100−(100−25π+100−25π)</p><p></p><p></p><p>$

$\sf \: = 50π−100$

$\dashrightarrow \sf \red{57} {cm}^{2} \dashleftarrow$
