On a field whose length is 25 meters and width is 12 meters a house was built the shape of a square whose side is 9 meters. What’s the area of the garden?
The field is a rectangle whose length is 25 meters and width is 12 meters. The area is L × W = 25 × 12 = 25 × 4 × 3 = 100 × 3 = 300 m2
The field covered by the house is a square with the side of 9 meters. The area is 9 × 9 = 81 m2
The garden’s area will be 300 – 81 = 219 m2
