Area of square
=

(Diagonal)2

2

=

12√6×12√6

2

= 432 sq. metre
∴ Area of rectangle
= 432 sq. metre
Breadth of rectangle = x metre
∴ Length = (x + 6) metre
∴ (x + 6) × x = 432
⇒ (x + 6) × x = 24 × 18
⇒ x = 18 metre
∴ Perimeter of rectangle
= 2 (x + 6 + x)
= 4x + 12
= 4 × 18 + 12 = 72 + 12
= 84 metre
