\(56\sqrt 2 \;m\)ঙ)
None of theseExplanation
Area of Rectangle = Length × Breadth ⇒ Area of Rectangle = 64 × 49 Given : Area of Rectangle = Area of Square let the side of the square be "a" Area of square with side "a" = a 2 ⇒ Area of Rectangle = 64 × 49= Area of Square = a 2 ⇒a = = 8×7 = 56 m The length of the diagonal of the square with side a is a ⇒ length of the diagonal of the square is 56 Hence Option (4)Related questions
