Given side of the square park = 66 m

Hence area of square park = side × side

= 66× 66 = 4356 sq m

Given length of rectangular park, l = 90 m

Let the breadth of the rectangular park be "b"

Area of rectangular park = l × b

But given area of rectangular park = area of square park

⇒ 90 × b =4356

⇒ b = 4356/90 = 48.4

Hence breadth of the rectangular park is 48.4 m.
