​

Answer 1

Answer:

Step-by-step explanation:

(i) Length = 24.5 m

Breadth = 18 m

   

  ∴ Area of the rectangle = Length × Breadth

                                = 24.5 m × 18 m

                                = 441 m2

             

 (ii) Length = 12.5 m

Breadth = 8 dm = (8 × 10) = 80 cm = 0.8 m     [since 1 dm = 10 cm and 1 m = 100 cm]

     

     ∴ Area of the rectangle = Length × Breadth

                                   = 12.5 m × 0.8 m

                                   = 10 m2
