- First, calculate the area of the rectangle.

- The length is 11 cm.

- The width is 5 cm (since it's 6 cm less than the length).

- Area = length × width = 11 cm × 5 cm = 55 cm².

- Next, find 4/5 of the area of the rectangle:

- (4/5) × 55 cm² = 44 cm².

- The perimeter of the square is equal to 44 cm.

- For a square, Perimeter = 4 × Side.

- So, 4 × Side = 44 cm.

- Side = 44 cm / 4 = 11 cm.

Option:4, 11 cm is the length of the square.
