Proof:- In 

Or, AB2 = AC X AD ---------------------(i)

Similarly 

Or, BC2 = AC X CD ---------------------(ii)

Adding (i) and (ii) we get

AB2 + BC2 = AC X AD + AC X CD

= AC X (AD + CD)

= AC X AC

= AC2

Or, AC2 = AB2 + BC2

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.
