Length of rectangle = 5dm 4cm = 5 × 10 + 4 = 54 cm
and,
Breadth of the rectangle = 3 dm 4 cm = 3 × 10 + 4 = 30+4 = 34 cm [ 1DM = 10 CM]
Area of rectangle = Length× Breadth = 54 × 34 = 1836 cm².
Side of square = 4dm 5 cm = 4 × 10 + 5 = 45 cm
Area of square = (Side)² = (45)² = 2025 cm².
Therefore,
The difference between the area of rectangle and area of square = 2025 - 1836 = 189 cm².
