Let side of Square be X

diagonal will be x√2

x√2=13

so x will be 13/√2

Given:

Diagonal of Square = 13 cm

For a square , each of whose side is 'a' .

Diagonal of Square = √2 a

13 = √ 2 a

a= 13 /√2

a= (13× √2/ √2 × √2)

[ By rationalising the denominator]

a= 13√2 /2

a= 6.5√2

Hence, the side of a square is 65√2 cm

Answer 2

(Diagonal)^2 = (side)^2 + (side)^2
13^2 = 2a^2
169/2 = a^2
a= 13/root 2
Side of square is 13root2/2 or 13/root2
