Question

the length of a diagonal of a square is 20 cm find the area of the square

​

Answer 1

$\huge\mathbb{SOLUTION:-}$

$\sf\underline{\purple{\:\:\:\: Given\:\:\:\:}}$

$\sf\bullet Diagonal\:of\:Square=20cm$

• Now the Area of square

$\sf\bullet{\boxed{\sf{Area\:of\:square=side{}^{2}}}}\\ \\ \sf\bullet or\:Area\:of\:square=\dfrac{1}{2}\times (diagonal){}^{2}$

So Area

$\sf\implies Area=\dfrac{1}{2}\times (20){}^{2}\\ \\ \sf:\implies Area=\dfrac{1}{\cancel2}\times \cancel{400}\\ \\ \sf:\implies Area= 200cm{}^{2}$

$\sf\bullet{\underline{Area\:of\:square=200cm{}^{2}}}$
