Answer:
Length of rectangle = 25m
Breadth of rectangle = 18m
Area of rectangle = 25m×18m
= 450m²
Length of rectangle = 8.4cm
Breadth of rectangle = 3.2cm
Area of rectangle = 8.4cm×3.2cm
=26.88cm²
Length of rectangle = 20cm
Breadth of rectangle = 15cm
Area of rectangle = 20cm×15cm
=300cm²
Length of rectangle = 2m
Breadth of rectangle = 15cm = 15/100cm = 0.15m
Area of rectangle = 2m×0.15m
=0.3m²
