Question 13
Mr. Green has rectangular land of area 600 m². Following the design below, he builds a square farmhouse of area 144 m² and two identical ponds of area 81 m² each. The rest is his garden. Find the garden’s perimeter.
Grading clarification: the supplied worked solution treats the two depicted ponds as squares. This package uses that square-pond interpretation. The word “identical” alone, without the shape information, would not determine the perimeter uniquely.
