Question

if the length of a diagonal AC of a square ABCD is 5.2 cm, then the area of a square is

Answer 1

Answer:

We have,

Side of square =2Diagonal

∴ Area =(2Diagonal)2

=2(5.2)2

=227.04

=13.52cm2

Answer 2

$\huge\underbrace\mathtt\red{❥︎AnSweR:-}$

☘︎We have,

☘︎Side of square = Diagonal/√2

$∴ Area \: = { (\frac{diagonal}{ \sqrt{2} } )}^{2}$

= (5.2)^2/2☘︎

= 27.04/2☘︎

=13.52cm^2☘︎

☁︎Hence, Option B is the correct answer.☁︎
