Let side of the square = 10m ∴ Area of the square = 100m² and Perimeter of the square = 10 x 4 = 40 m After change, side of the rectangle = 15 m and 8 m ∴ Area of the rectangle = 15 x 8 = 120m² and Perimeter of the rectangle = 2 (15 + 8) = 46 m ∴ Area of the rectangle = 120% of the area of the square and Perimeter of the rectangle = 115% of the perimeter of the square
