Question

in a square adjacent sides are (2a-3)and (a+6) find the value of a also find the length of the diagonal

Answer 1

We know that the all sides of a square is equal.

So,

⇒ ( 2a - 3 ) = ( a + 6 )

⇒ 2a - a = 6 + 3

∴ a = 9.

Side = ( 2a - 3 )

        = ( 2 × 9 - 3 )

        = ( 18 - 3 ) = 15.

Diagonal of a square = √2 × side

                                  = √2 × 15

                                  = 15√2.
