Question

if the diagonal of square is 13 cm then find its length of the side​

Answer 1

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
